The highly anticipated first book of The Wicked Powers, the final Shadowhunters trilogy! #1 New York Times bestselling author Cassandra Clare brings the saga that began with The Mortal Instruments to a stunning conclusion.

It's Drusilla Blackthorn's third year at Shadowhunter Academy when a chance encounter at a nightclub turns into a kidnapping. 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 humour that makes Cassandra Clare the reigning queen of romantasy.
