Dru finds herself held prisoner by Prince Ash Morgenstern in the land of Faerie, a place that proves just as dangerous as it is beautiful. Despite herself, Dru is drawn to Ash and the darkness that seems to surround him—but one false move could cost her life.

Meanwhile, a shocking disappearance rocks the foundations of the Shadowhunter world. Kit Herondale and Ty Blackthorn must set aside the bitterness that lingers between them and join forces on a perilous quest to save everything they cherish.

The first installment of the long-awaited concluding trilogy to the Shadowhunter Chronicles has all the nail-biting adventure, heart-pounding romance, and trademark humor that makes Cassandra Clare the reigning queen of YA romantasy.
