And each victim has a string of numbers tattooed on their wrist. All of the victims were killed in public, yet the killer does not show up on any security feed. But even with the team's unique profiling talents, these murders seem baffling: unlike many serial killers, this one uses different methods every time. In All In, Cassie and the Naturals are called in to investigate a string of brutal murders in Las Vegas. Forced deeper into a murderer's psyche than ever before, will the Naturals be able to outsmart the enigmatic killer's brutal mind games before this copycat twists them into his web for good? But when victims of a brutal new serial killer start turning up, the Naturals are pulled into an active case that strikes too close to home: the killer is a perfect copycat of Dean's incarcerated father-a man he'd do anything to forget. In Killer Instinct, Cassie hopes she and the rest of her team can stick to solving cold cases from a distance after barely escaping a confrontation with an unbalanced killer obsessed with her mother's murder. Caught in a lethal game of cat and mouse with a killer, the Naturals are going to have to use all of their gifts just to survive. And when a new killer strikes, danger looms close. Soon, it becomes clear that no one in the Naturals program is what they seem. But what Cassie doesn't realize is that there's more at risk than a few unsolved homicides-especially when she's sent to live with a group of teens whose gifts are as unusual as her own. That is, until the FBI come knocking: they've begun a classified program that uses exceptional teenagers to crack infamous cold cases, and they need Cassie.

But, it's not a skill that she's ever taken seriously. Piecing together the tiniest details, she can tell you who you are and what you want. In The Naturals, seventeen-year-old Cassie is a natural at reading people.
