The #1 New York Times bestselling author of Year One and Of Blood and Bone concludes her stunning trilogy, which The New York Times Book Review praised as ‘a match for end-of-the-world classics like Stephen King’s The Stand.’ After the sickness known as the Doom tore across the globe and civilization crumbled in its wake, people had no choice but to turn back to the land to survive. But in this desolate, radically altered world where magick has become commonplace, hunger is not the only danger. Fallon Swift cannot live in peace until she frees the hunted and the prisoners locked up in laboratories, brutalised for years on end. She is determined to save even those who have been complicit in this evil out of fear or weakness – if, indeed, they can be saved. Strengthened by the wisdom of her mentor, Mallick, and the troubling yet stubborn bond she shares with her fellow warrior, Duncan, Fallon has already succeeded in rescuing countless shifters, elves, and ordinary humans. Now she must help them heal – and rediscover the light and faith within themselves. For although Fallon, from the time of her birth, has been The One, she is still only one. And as she faces down an old nemesis, sets her sights on the enemy’s stronghold, and pursues her destiny – to finally restore the mystical shield that once protected them all – she will need an army behind her.
