#1 New York Times and USA TODAY bestselling author Natasha Preston is back with another pulse-pounding, twisty read! Haunted by the past . . . Penny's trying to forget about her ex, Nash. His father was arrested for the brutal murder of four teenagers on Devil's Night last year. Penny's parents have forbidden her to have anything to do with Nash or his family. It's hard not to think of what happened as spooky season gets underway-but she's trying. That stops when she goes to the Halloween store with her friends to find a costume. What she finds instead is ripped from a horror movie: a girl from school bleeding out on the floor of a dressing room. Stabbed. Is a copycat killer on the loose? The adults are saying no. But Penny knows better.
