Thirteen was never so unlucky. When missing children turn up dead with their hearts missing, it's up to Ivy Teller and Sammy Lopez to find out who or what is lurking in the Forest of Whispers. They thought folktales were just stories meant to scare children, but they're about to find out what happens when a demon of lore is real. Inspired by the legend of the Jersey Devil. The Jersey Devil is the thirteenth child of a witch.
