• Sarah J. Maas' "A Court of Splintered Harmony" came out on Tuesday.
• The book largely sets the scene for future installments, but it's full of important details.
• Readers learned more about Azriel's shadows and Nesta's possible connections to the prison.

It's "ACOTAR" time, people.

On Tuesday, Sarah J. Maas released "A Court of Splintered Harmony," the sixth book in the "A Court of Thorns and Roses" series. The book is the first volume in a larger story arc within the world of "ACOTAR," which Maas has titled "The Valkyrie Cycle."

Maas took readers back to Prythian in the novel, picking up after the events of "A Court of Silver Flames" and "House of Flame and Shadow," the third book in her "Crescent City" series. High Lord Rhysand, High Lady Feyre, and their Inner Circle are working to protect humans and keep Koschei, a death god, from escaping the enchanted lake where he's trapped. There's plenty of turmoil for the Inner Circle at home, too, though, from power struggles to love triangles.

Luckily, parts two and three of "The Valkyrie Cycle" come out in January 2027 in one volume called "A Court of Forgotten Melody," so fans won't have to wait too long to see what happens next in "ACOTAR."

In the meantime, "ACOSH" was packed with plot twists and shocking reveals, so read on for a look at the most important details you may have missed.

Spoilers for Maas' works ahead.

Koschei the Deathless

Koschei was positioned as the looming villain in Maas' latest novel, though the character has yet to physically appear on page. (He made a brief appearance in a shadowy form in "A Court of Silver Flames.")

In "ACOSH," Vassa, a human queen trapped by Koschei, tells Feyre and Rhysand that he projects his voice to others rather than allowing anyone to get close to him, with the notable exception of Feyre's father, according to Lucien.

Vassa also shared that all the women Koschei keeps as prisoners are distant descendants of the fae warrior who initially trapped him at the lake.

It's not the first time Maas has alluded to the mysterious female fae who trapped Koschei and his sister Stryga. The Bone Carver, their brother, spoke of her to Feyre and Cassian, Rhysand's general, in "A Court of Wings and Ruin," saying, "Clever, that fae warrior. Her bloodline is long gone now — though a trace still runs through some human line." He also said she could have been his "salvation," though he doesn't explain how.

The Bone Carver said her name had been forgotten to history, but perhaps Koschei will reveal her identity in future Maas works.

The Bone Carver also said he and his siblings came from another world, much like the Asteri (known as the Daglan in Prythian). It's possible they originate from the world on which Maas' "Throne of Glass" series takes place, considering Maas has been tying her three fantasy worlds together in her recent works.

Azriel's shadows

"ACOSH" offers readers a more in-depth look at Azriel's shadows. Through his narration, Maas reveals that the shadows are sentient, exploring the world for Azriel and telling him everything from the weather to how people are feeling.

They also display feelings toward different characters throughout the novel, investigating intruders in the Night Court or avoiding others, such as the shadow creature Erebos.

They seem either unable or unwilling to come anywhere near Elain Archeron. They won't enter any room she is in, whether that be a dining room or a temple.

Azriel thinks his shadows' disappearance is "a gift," but their absence puts him in danger twice in "ACOSH."

First, he does not sense the creature Bryaxis approaching during baby Nyx's naming ceremony, thinking to himself that his shadows weren't there because "Elain had chased them away." Bryaxis was able to attack the Inner Circle in part because Azriel didn't feel her coming.

Hours later, Azriel's shadows do not warn him that Lucien, Elain's mate, is outside her bedroom, as they had "fled the moment he'd sought out Elain," again leading to trouble for the Shadowsinger. He and Lucien physically fight during the interaction, and Rhysand kicks Azriel out of the house. Morrigan, Rhysand's third and the object of Azriel's longing for years, also scolds him, and the interaction marks the last time he sees Elain in the novel, who ends up fleeing Prythian in the aftermath.

In contrast, his shadows are thrilled to see someone else a few pages later: Gwyn. Azriel ventures to the House of Wind to retrieve some of his belongings after the incident, and when he hears singing, his shadows "surged past his feet, a black tide racing ahead," sprinting to Gwyn. The shadows then gather at Gwyn's feet, watching her until Azriel summons them back.

Perhaps Maas will explore what Azriel's shadows know about each female in future works.

Nesta and the prison

As she is in "A Court of Silver Flames," Nesta Archeron is central to the plot of "ACOSH," quarreling with the Inner Circle and ultimately saving them when Bryaxis comes back to town.

She is also drawn to the prison throughout the novel, which she explored extensively with Bryce Quinlan in "House of Flame and Shadow." During their journey there, they discovered that the prison had once been an eighth court that could have served as the Dusk Court.

Maas leans into dusk imagery each time Nesta visits. During one trip to the prison, she looks "to the purpling eastern sky. To the first star of evening. To the darkness, the night growing beyond it."

She also sees that the prison is along "that northern horizon, stained with a dazzling blend of encroaching night and lingering day."

It also appears that Nesta and Rhysand may share a connection to the prison. When Nesta tries to winnow to the island, she almost drowns and sees something "glimmering" on the floor below, believing it is calling, "Find me," to her. Rhysand saves her, telling Nesta he heard her mentally scream, "Find me," to him.

It's possible Nesta was confused and shouting out mentally for aid, but it's also possible Nesta and Rhysand were being beckoned by the same Made object. Rhysand controls the prison through his bloodline, so it's plausible that a Made object associated with it is calling to them both.

In addition to the dusk imagery she associates with her, Maas also ties Nesta to the word "splintered," which appears in the novel's title. Nesta asks her house for guidance on her relationship with Cassian, and the house offers her a pile of splinters from a punching block she broke during her training. For Nesta, the demonstration is meaningful.

"The House couldn't have chosen a better symbol of where she and Cassian stood," she thinks to herself. "The training, the determination, the love that had grown between them — all shattering not due to some outside force, but because of her."

The splinters lead her to open up to Cassian about her feelings, but they also may indicate that "Splintered Harmony" in the title has a lot to do with Nesta and Cassian.

Other imagery

Nesta isn't the only character Maas associates with specific imagery throughout the book.

Maas repeatedly associates Elain with spring. Azriel describes Elain as "a whisper of spring" and "as lovely as a spring dawn." Lucien says she has a "floral scent," and she is seen tending flowers and decorating Nyx's naming ceremony with them in the book.

Maas also introduces the concept of Feyre and her son, Nyx, as a flash of silver in the night court.

Clotho made "a braided, silvery piece of fabric" for Feyre and Rhysand to use during Nyx's naming ceremony, telling Nesta it was one of a kind as she gave it to her to pass on to the High Lord and Lady. Later, when Lucien is dining at their home, he notices a tapestry Feyre has hung on the wall, saying his magical eye can see the silver thread moving in it.

During his chapter, Lucien also says his magic eye has shown him a silver aura around Feyre since the moment he met her, describing it as a "silvery brightness" that intensified as Feyre found love and joy at the Night Court.

Gwyn's power

During both passages in which Gwyn appears in the novel, she is singing, which seems significant given the musically themed titles of books six and seven in the "ACOTAR" series.

Maas gives indications that Gwyn's music may have magical properties.

Nesta notices that Gwyn's singing voice is more powerful than the voices of her fellow choir singers, saying, "Gwyn could have carried the entirety of the song herself, that mezzo-soprano voice so rich and resonant that it seemed to effortlessly burst from her."

Likewise, Azriel describes Gwyn's voice as "otherworldly" and "strange and yet familiar," adding that "starlight spilled down the steps, almost in answer to the song" as she sang.

Maas also seems to liken Gwyn to light, particularly when she's singing.

When Nesta watches Gwyn sing, she notes that she "shone" and seemed to "radiate light," thinking to herself that "the candlelight seemed to bend toward" her friend. Similarly, when Azriel sees Gwyn at the House of Wind, he describes her hair as "shining in the starlight," remarks on her "bright gaze," and notes that her eyes were lit by the stars above.

Similarities between Azriel and Gwyn

Throughout "ACOSH," Azriel describes himself as a monster because of his shadow-wielding abilities and talent at extracting information from enemies. He says he was often called a monster or a demon in his youth, and he came to think of himself that way.

"He was a monster — merely a creature," Azriel thinks of himself in the text. "Best left skulking in shadows. Most suited to collecting information through subterfuge or pain."

Other characters in "ACOTAR" have said people think of them as monsters, like Rhysand, but the only other character in "ACOSH" who seems to genuinely think of herself as monstrous is Gwyn.

In a chapter told from her perspective, Gwyn reveals that she has been avoiding training with the Valkyrie and the world outside the temple because she relished killing enemies during the Blood Rite. Her chapter ends with her thinking she hears Bryaxis laughing at her, "like it knew it wasn't the only monster down here."

Maas also highlights parallels between Azriel's and Gwyn's powers in "ACOSH."

Azriel talks about his Siphons, which help control his magic, repeatedly in the book. He notes that they are all "a cobalt bordering on turquoise," for a reason he has never known.

Later, Gwyn throws her Invoking Stone at Azriel when he startles her, which he says "glittered with turquoise fire." Gwyn's eyes are a similar shade, described as teal throughout Maas' works.

In addition to the similar coloring of the Siphons and the Invoking Stone, Azriel notes that the Stone has a similar magical feel, thinking he "never realized how much presence it seemed to have, like his Siphons, but wholly different," he said.

Azriel quickly returns the Stone to Gwyn after their brief interaction, but Maas may explore the similarities between the two down the line.

Parallels with Mor

At the end of "ACOSH," Elain begs Mor to take her with her to Vallahan, and Mor agrees, seeing that Elain needs space from Azriel, Lucien, and the Inner Circle to figure out what she wants.

It's not the first time Mor has helped an Archeron sister get some distance from a male causing her problems.

In "A Court of Mist and Fury," Mor whisks Feyre away from males twice. First, she rescues Feyre from the Spring Court after Tamlin traps her in his house. Later, Mor winnows Feyre to the cabin after she discovers that Rhysand had been keeping the fact that they were mates a secret.

She does the same for Nesta in "A Court of Silver Flames," winnowing Nesta to Emerie's home when she needs a break from Cassian. She brings Gwyn to the house, too, so Nesta has the support she needs during her turmoil.

For Feyre and Nesta, that time away allowed them to figure out how they felt about the males in their lives, positive or negative. Hopefully, Elain gets the same clarity from her space.

• Sarah J. Maas' sixth "A Court of Thorns and Roses" novel comes out on October 27.
• Book seven will follow on January 12, 2027, as Maas first announced in March 2026.
• Maas has been revealing which characters will tell the story on her social media in recent days.

Sarah J. Maas fans, it's finally time to go back to Prythian.

The sixth "A Court of Thorns and Roses" novel, titled "A Court of Splintered Harmony," will hit bookshelves on October 27 after months of anticipation. It will be quickly followed by book seven, "A Court of Forgotten Melody," on January 12, 2027.

It's been five years since Maas last released an "ACOTAR" book, and the novel is eagerly awaited not only by fans but also by Maas' publisher, Bloomsbury. The company's sales fell 10% for the 2025-2026 fiscal year because Maas didn't release a new book, Publishers Weekly reported.

Both Bloomsbury and Maas have been sharing teasers on social media about "A Court of Splintered Harmony" in the lead-up to its publication, with Maas revealing which characters will be narrating the novel (after asking fans to stop sharing any leaks of book six).

Here's everything we know about "ACOTAR" six so far.

Warning: Some spoilers for Maas' work — including "ACOTAR" and "Crescent City" — ahead.

Maas is releasing the sixth 'A Court of Thorns and Roses' story in multiple volumes

In March 2023, Bloomsbury announced that Maas had signed a deal for three more books with the publisher. At the time, she was already under contract for four titles, including "House of Flame and Shadow," the third installment in her "Crescent City" series, published in January 2024. Readers didn't find out what the next book she would write would be until her March 2026 appearance on the "Call Her Daddy" podcast with Alex Cooper.

She told Cooper she finished the sixth "ACOTAR" book while writing in Montana over the summer of 2025, but she didn't share details about it because of its nontraditional release structure.

"This book's coming out October 27, and then on January 12, like two months later, I can't do math, whatever that is, the next ACOTAR book will be coming out," Maas said. "So there will be two books within, like, a very short span."

As her fans will know, Maas' books are typically split into parts, separating different sections of the story she is telling. However, when it comes to the sixth "ACOTAR" story, Maas said the individual parts became longer than she anticipated as she started writing, with part one coming in at 400 pages at one point.

As she continued writing, Maas decided the parts didn't have to be in a single physical book.

"What if this book was really long?" she said. "What if it took me more than a thousand pages to tell the story that needed to be told, the arc that I wanted to create from start to finish?"

Maas said the story for "ACOTAR" six was ultimately divided into four parts, though it is still one cohesive story. Part one is the novel Bloomsbury will publish on October 27, 2026, and parts two and three will be published together on January 12, 2027. Maas has yet to write or give a publication date for part four, but she told Cooper all three volumes would be published "in a very short time."

"It's meant to be read, ideally, as one massive, massive story as opposed to in a trilogy," she said. "It's not a trilogy. Like, arcs aren't wrapped up."

Maas finally shared some details about the books in August 2026

On August 16, Maas cleared her Instagram of all its posts, changing her profile photo to a black-and-white illustration of a monster and a spider. Then, on August 17, she shared the covers and titles of books six and seven on social media.

The "Splintered Harmony" cover features a pink-and-orange backdrop with a sketched drawing of a monster with teeth and bones, and the subtitle is "The Valkyrie Cycle: Movement I." The Valkyrie were introduced to "ACOTAR" in "A Court of Silver Flames," when Nesta Archeron brought the legendary all-female fighting squad back to life alongside her friends Gwyn and Emerie.

Maas posted the book alongside the tagline, "What was broken will be remade." The blurb shared on booksellers' websites reveals that the Night Court is facing new threats when book six opens: Koschei the Deathless, one of three legendary monster siblings introduced throughout "ACOTAR," and those willing to ally with him to claim the newly freed human lands.

The description also notes that there is tension among the members of the Night Court because of "recent betrayals and revealed truths," which they must work through if they want to defeat Koschei.

"A Court of Splintered Harmony" will be 352 pages and will include three bonus chapters from the "ACOTAR" series. Those bonus chapters were previously published in specific editions of Maas' novels, but they will be in all copies of "ACOSH," as the publisher shared on its social media on September 24. One chapter focuses on Feyre and Rhysand, one on Cassian and Nesta, and one on Azriel's experience on the Winter Solstice that takes place in "A Court of Silver Flames."

Teasers from the new book

In mid-September, Bloomsbury began sharing quotes from "A Court of Splintered Harmony," offering more insight into the novel than the vague blurbs.

It released six quotes in total, and the first, shared on September 17, revealed that at least some of the novel will be told from Lucien Vanserra's perspective.

"Lucien's heart thundered, throat drying out," the quote read. "Maybe this had been a terrible idea."

Lucien has only played a supporting role in the "ACOTAR" books so far, but Maas has been teeing up his expanded role in her books through his unaccepted mating bond with Elain Archeron, Feyre's middle sister, and his connection to Koschei. He serves as an emissary to the human lands for the Night Court in "ACOSF," alongside Jurian and Vassa, a human queen who was sold to Koschei and cursed to turn into a firebird each day. It would be surprising if Vassa — and by extension Lucien — weren't involved in fighting against Koschei in book six.

Likewise, the final quote Bloomsbury shared on October 9 appeared to confirm that Azriel will narrate some of "ACOSH." The quote didn't include his name, but the unnamed narrator was communicating with shadows: "'We are here,' the shadows whispered in his ear. 'We are always here.'"

Azriel is a Shadowsinger in the "ACOTAR" world, with his shadows being described as keeping him company and whispering to him as he serves as the Night Court's spymaster.

No other passage shared by Bloomsbury names a narrator, but interestingly, the quote shared on September 28 asks if it is "possible for mates to…un-mate" if a bond were to "fracture deeply enough" that it cannot be repaired.

Lucien and Elain's mating bond is strained because Elain has yet to accept it, so some fans think the comment is about them. At the end of "House of Flame and Shadow," though, Nesta and Cassian were at odds, so others think the quote hints at tension between the pair (more on that in a minute).

On October 24, Bloomsbury also shared a sneak peek of the map that sits at the front of "A Court of Splintered Harmony." It shows new locations in the Night Court, such as Sangravah, and in the Autumn Court, including the Forest House and the Thorn-Wood. It also offers a look at the faerie realms outside Prythian, such as Vallahan. Koschei's lake is in the other faerie realms, sitting among the open fae lands in front of a mountain range.

Maas chimes in

Maas' Instagram was quiet after she announced the titles of her books, until October 19, when she took to her Instagram story to ask fans not to share leaks of "A Court of Splintered Harmony."

"I know how much you love these books and these characters; I know you've been waiting for a long time to know what comes next," she wrote. "That love for these stories is exactly why I'm requesting that you please, please don't share leaks."

"Nothing about this release is meant to feel like a secret that needs to be found out," Maas went on. "Publishing a book takes time and effort from so many hardworking people to get it into your hands. Throughout this long process, everyone involved has been dedicated to keeping things from being spoiled, but sometimes things happen, and it is beyond disheartening to see out-of-context moments take away from all of you who have waited so patiently."

"All I'm asking for is just a bit more of that patience — until you can get everything in its fullness, the way it's meant to be read," Maas said.

Representatives for Maas did not respond to a request for comment on the Instagram story, and Maas did not specify which images spreading online contained authentic leaks of the book.

However, in the week leading up to the book's release, she posted a short video each day to reveal which of her characters would narrate "A Court of Splintered Harmony." Each video featured a quote from the character set against a sketch of the monster on the novel's cover. The backdrop for the first drop was gray, but it grew progressively darker, revealing stars with each post.

The narrators are:

Feyre

Feyre was the narrator for the first four "ACOTAR" books, telling the story from a first-person perspective. Like books one through four, the passage Maas shared was in the first-person perspective, unlike the other quotes:

"My body wouldn't move. Couldn't move. I could do nothing to help him, nothing at all, and I would die from it, this despair and agony. Please, I tried to beg the darkness, please. Anything. I'd give anything for him to be safe. My life, my territory, my — would you give that too?"

Maas provided no further context about the quote, though fans were quick to point out that the inner monologue seemed like what Feyre would have been thinking when she gave birth to her son, Nyx, as she and the baby almost died because he was born with wings. Rhys also nearly lost his life, as he and Feyre bound their lives together at the end of "A Court of Wings and Ruin." Nesta saved them all by returning her power to the cauldron, but the passage could be a flashback to the scene from Feyre's perspective.

Cassian

Cassian was one of the two narrators of "A Court of Silver Flames," which told his and Nesta's love story. His passage from the new novel appears to show him and Nesta at odds:

"So Cassian let her go. Let her keep walking down the hall, and out the front door. Nesta didn't look back at him. Not once."

It's unclear what they may be fighting about, though Cassian was disapproving of Nesta's actions in "House of Flame and Shadow." Details below.

Nesta

In the quote Maas shared from Nesta, the eldest Archeron sister is drawn to some unnamed power.

"On trembling legs, head spinning, Nesta managed to get to her feet. Maybe whatever called for her over the northern horizon was a siren song, luring her away from what mattered, who mattered. Come, it beckoned, but to where? To what end? More shadows and loneliness and secrets? It would consume her, if she let it."

Lucien

Maas' quote from Lucien was more specific than the one Bloomsbury shared, shedding light on the fire-wielder's frustration with Feyre.

"Lucien ran a hand through his hair. Tamlin had saved him. And then Lucien had rebuilt himself, his life. Only for Feyre to bring it all crumbling down."

Lucien is likely reflecting on Feyre's actions in "ACOWAR," when she brought down the Spring Court after Tamlin made a deal with the King of Hybern to get her back.

Gwyn

Gwyn is haunted by memories of her past in the sneak peek Maas offered from her portion of the novel.

"Gwyn staggered back from the railing, from the darkness, fingers fumbling for the invoking stone in her pocket. It was glowing and warm to the touch in a way that had nothing to do with its proximity to her flesh. You are here, the stone seemed to affirm, you are safe. The past cannot harm you. Gwyn shook her head. She was inclined to disagree."

Gwyn may be in the library where she works, as readers saw her and Nesta fleeing a dark force there in "A Court of Silver Flames."

Mor

At the end of "A Court of Frost and Starlight," Mor set off for Vallahan, another fae realm, to attempt to get the leaders there to sign a new treaty between humans and fae. She appears to be continuing that work in "A Court of Splintered Harmony," based on the teaser Maas shared about Mor, and offering more detail about her power, which is simply referred to as "truth" in "ACOTAR."

"She flexed her hands at her sides, working out the faint trembling in them. It was a fool's errand. She knew it — Rhys and Feyre knew it. Vallahan would know it, too. But she'd try. One last time. Mor sucked in a breath, an ancient, night-kissed power awakening from its slumber deep within her. Different from Rhys's, older."

Azriel

Maas confirmed Azriel was a narrator for the book the day before its release, writing of his Illyrian heritage:

"You are an Illyrian, Azriel — the wind sings through your very blood. You cannot be caged. You cannot be broken. They lock you away because they fear you."

The quote seems to refer to Azriel's childhood, as he spent his early years locked in his father's home, unable to learn to fly.

More clues about 'ACOTAR' 6 narrators

It makes sense that Nesta and Gwyn will be central to Maas' new books since the novels are part of "The Valkyrie Cycle." The Valkyries were a central focus of "A Court of Silver Flames."

The book ushered in a new era for the series, as it was told from Nesta's perspective. Maas again focused on her in "House of Flame and Shadow" in her "Crescent City" series.

The "recent betrayals and revealed truths" mentioned in the description of "A Court of Splintered Harmony" could refer to Nesta's actions in "HOFAS." Specifically, the "revealed truths" may reference the resurrection of the long-forgotten Dusk Court in Prythian, which they discover Rhysand is an heir to, while the "recent betrayal" against the Night Court could be Nesta's lending the Mask of the Dread Trove to Bryce Quinlan, the "Crescent City" protagonist, without Rhysand and Feyre's permission.

Bryce also gave Nesta the sword Gwydion at the end of "HOFAS," telling her she thinks she was meant to have it when she returns the Mask. Nesta shared with Bryce in the same scene that Cassian is the most upset with her of everyone for her actions.

It seems Maas was setting up a continuation of Nesta's story for her next "ACOTAR" story in the scene, which may see her explore her power and connections to the fae of the Dusk Court.

You can read a more detailed breakdown of what to remember from Maas' previous works ahead of "ACOTAR" six here.

Elain's role in future 'ACOTAR' books

One notable character doesn't yet have a confirmed POV in the new novel: Elain Archeron.

In "A Court of Silver Flames," Elain had settled into life at the Night Court, refusing to explore her mating bond with Lucien or her Seer powers. She also seems to have an attraction to Azriel in the text, with the pair almost kissing in his bonus chapter. However, Maas juxtaposes their connection with the ill-fitting aspects of life at the Night Court for Elain during a visit to the Court of Nightmares in "ACOSF."

Maas told Eva Chen during an appearance on "Live Talks Los Angeles" in February 2021 that she planned to write a book from Elain's perspective. She also discussed Elain on "Call Her Daddy" in March 2026, saying Lucien's involvement in bringing Elain to the fae world is a barrier to their relationship. Maas said she was "interested" as a writer in exploring what it meant for someone not to desire to be mated.

It's surprising that Elain is not confirmed to have a POV in "A Court of Splintered Harmony," given Maas' past comments, the brewing tension surrounding Elain, and the fact that both Lucien and Azriel have POVs in the book. Elain may have a surprise chapter in the book, or she could narrate future installments in the series.

Readers will have to wait and see what role Maas plans for Elain to play in the new "ACOTAR" books.
