Killer Instinct (The Naturals, #2) by Jennifer Lynn Barnes

The second book in The Naturals series, Killer Instinct continues the thrilling story of Cassie Hobbes and her fellow teen profilers working with the FBI. After surviving a deadly encounter with a serial killer, Cassie is struggling to regain a sense of normalcy—but in their line of work, normal doesn’t exist. A new serial killer is on the loose, one who mimics the infamous crimes of Dean’s father, the notorious Daniel Redding. As the team investigates, tensions rise, especially when the FBI assigns a new agent to oversee their work—someone who doesn’t trust teenagers solving murders. Cassie must use her profiling skills to uncover the truth, but with danger closing in, every clue brings them closer to a killer who may be hiding in plain sight. Packed with high-stakes suspense, psychological twists, and intense character dynamics, this sequel raises the stakes and keeps readers on edge until the very last page.
