Cassandra Clare to Release Five New Books Through Alfred A. Knopf

Fans of Cassandra Clare’s books have more stories to look forward to, including the final entries in the Shadowhunter Chronicles.

Alfred A. Knopf Books for Young Readers, an imprint of Random House Children’s Books, will publish five new books from #1 New York Times and USA Today bestselling author Cassandra Clare, whose novels have sold more than 40 million copies worldwide, been translated into 43 languages, and published in more than 60 countries.

The new publications will begin in Spring 2026 with the first book in THE WICKED POWERS trilogy, the sixth and final series in Clare’s 23-book young adult fantasy franchise the Shadowhunter Chronicles. Also slated for publication with Knopf is a brand-new YA romantasy duology, IN FIRE FORETOLD.

Cassandra Clare mesmerized readers across the globe with the publication of City of Bones (2007), the first book in the Mortal Instruments series, and was quickly dubbed the “New Queen of Fantasy” by the Wall Street Journal. The Mortal Instruments became the basis for the far-reaching Shadowhunter Chronicles, an intricately drawn world that has seen global success and has been adapted into both a feature film and television show.

The books follow the Shadowhunters, a secretive race of humans born with angel blood, whose mission is to eliminate the demons that plague the Earth. Knopf’s first publishing collaboration with Clare, THE WICKED POWERS (Spring 2026), will follow Kit Herondale, Ty Blackthorn, and Drusilla Blackthorn from the Dark Artifices series as they are drawn into the final massive conflict between the demons and the angels.

IN FIRE FORETOLD is a pulse-pounding YA romantasy duology set in a new world with entirely new characters. The story centers a young woman who must learn to control her dangerous magical abilities in order to save her kingdom, all while finding herself torn between two brothers—the kingdom’s princes, born to a cursed royal bloodline. The publication date for IN FIRE FORETOLD, as well as news of additional books to come from Cassandra Clare and Knopf, will be announced.
