KILLER INSTINCT

The Naturals series continues with Killer Instinct, a darker, more intense chapter in Cassie Hobbes’ journey. After facing a harrowing serial killer, Cassie is back with her team of teen profilers, but the FBI now introduces a chilling new element—Agent Locke, who brings a personal connection to infamous serial killer Dean's father. The team's latest case is unlike anything they've ever encountered: a brutal murderer who mimics notorious killers from the past. As Cassie hones her profiling skills, she struggles to separate herself from the horrors she uncovers, particularly as her past comes back to haunt her. Dean, her fellow profiler, is caught in a personal nightmare as the new case mirrors his own family's crimes. Their investigation becomes a race against time, and Cassie realizes that even within the safety of the team, danger is lurking. With deadly mind games and psychological tension building, Killer Instinct takes readers deeper into the darkness of criminal psychology.
