Bad Blood

Bad Blood is the fourth and concluding novel in Jennifer Lynn Barnes’s Naturals series, which follows a group of gifted teens whom the FBI recruits into a clandestine FBI program. Each member possesses an innate, specialized ability for solving crimes: Cassie Hobbes is a profiler, Dean Redding shares her talent, Lia Zhang is a human lie detector, Michael Townsend reads emotions, and Sloane Sheridan is a living encyclopedia of facts and statistics.

The series begins with The Naturals (2013), which follows the team’s formation by the FBI and their initial work in solving cold cases. In the second installment, Killer Instinct (2014), the team (Cassie, Dean, Michael, Lia, and Sloane) transitions from cold cases to active investigations, and they look into unusual murders that mimic those committed by Dean’s father, a notable serial killer who is incarcerated. In the third installment, All In (2015), the team travels to Las Vegas, Nevada, to hunt a serial killer whose methods connect to a complex mathematical pattern. In Bad Blood, their focus shifts to an active threat from a secret society of serial killers.
