Critical Content | Reported October 26, 2026
Readers waiting for another trip to Prythian have a date to circle: A Court of Splintered Harmony, the sixth novel in Sarah J. Maas’s A Court of Thorns and Roses series, is scheduled for release on Tuesday, October 27, 2026. As of October 26, the publisher still labels it a preorder.
What is confirmed about the new book
Bloomsbury’s official listing identifies the title as A Court of Splintered Harmony: The Valkyrie Cycle, Movement I. The publisher lists an October 27 publication date for a 352-page hardcover with ISBN 9781639739134. Availability may vary by retailer, format and region.
The description places a growing threat from Koschei the Deathless against a politically fractured world. Familiar alliances are strained while the Night Court faces consequences from earlier conflicts. Those details come from the publisher’s promotional synopsis, not leaked plot revelations.
Why this release has readers planning ahead
The ACOTAR series combines fantasy, romance and political intrigue, with a broad audience that discusses characters and theories online. A confirmed new installment can renew conversation about existing books without requiring a spoiler-heavy recap.
Bloomsbury’s series list also names a subsequent title, A Court of Forgotten Melody. The presence of another listing helps distinguish the October book from the series’ larger publishing plans. Readers should use publisher listings rather than rumor posts to confirm dates or editions.
Keep preorder news separate from reviews
Book covers, collector editions and preorders may appear online before publication. That does not mean the entire novel has officially been released, or that a circulating quotation is authentic.
As of this report on October 26, claims about the ending, reader reception and first-week sales cannot be verified as post-release facts. Those are developments to assess after October 27.
