And she's good at it. August Flynn is a monster who can never be human. No matter how much he once yearned for it. He has a part to play. And he will play it, no matter the cost.Nearly six months after Kate and August were first thrown together, the war between the monsters and the humans is a terrifying reality. In Verity, August has become the leader he never wished to be, and in Prosperity, Kate has become the ruthless hunter she knew she could be. When a new monster emerges from the shadows-one who feeds on chaos and brings out its victim's inner demons-it lures Kate home, where she finds more than she bargained for. She'll face a monster she thought she killed, a boy she thought she knew, and a demon all her own.
