Blackstone was once a thriving metropolis. But that was before the Dark Summer—a wave of violence and crime that swept through the city eight years ago, orchestrated by the fearsome Spinning Man. Now the Spinning Man is on the move again, and a boy named Caw is about to be caught in his web.
Caw has never questioned his ability to communicate with crows. But as the threat of a new Dark Summer looms, Caw discovers the underground world of Blackstone’s ferals—those with the power to speak to and control animals. Caw is one of them. And to save his city, he must quickly master abilities he never knew he had . . . and prepare to defeat a darkness he never could have imagined.
