Killer instinct

Seventeen-year-old Cassie Hobbes has a natural talent for profiling people — reading their behavior, predicting their next move. That ability earned her a place in an elite FBI program for gifted teenagers known as The Naturals. But when a new string of murders mirrors a notorious serial killer's past crimes, the team is pulled into a terrifying investigation that hits closer to home than ever before. As secrets unravel and danger escalates, Cassie must rely on her instincts — because this killer isn't just hunting victims… he's studying them.
