For years, Caw has lived on the streets of Blackstone City with only three crows for company. Caw has never known why he can understand the crows. But when he rescues a girl named Lydia from a vicious attack, he discovers others like him: ferals who can speak to certain animals. And some of them are dangerous. Now, the most sinister feral of all—the Spinning Man—is on the move again. To save his city, Caw must quickly master abilities he never knew he had… and prepare to defeat a darkness he never could have imagined.
