The Naturals

by Jennifer Lynn Barnes

Published 5 November 2013

Cassie Hobbes is not like most teenagers.

Most teenagers don't lose their mother in a bloody, unsolved murder.

Most teenagers can't tell who you are, where you're from and how you're likely to behave within moments of meeting you.

And most teenagers don't get chosen to join The Naturals.

Identified by the FBI as uniquely gifted, Cassie is recruited to an elite school where a small number of teens are trained to hone their exceptional abilites.

For Cassie, trying to make friends with the girls, and to figure out the two very different, very hot boys, is challenging enough.

But when a new serial killer strikes and Cassie is drawn into a lethal game of cat and mouse, she realises just how dangerous life in The Naturals could be.

All In

by Jennifer Lynn Barnes

Published 3 November 2015
Three casinos. Three bodies. Three days. After a string of brutal murders in Las Vegas, Cassie Hobbes and the Naturals are called in to investigate. But even with the team's unique profiling talents, these murders seem baffling: unlike many serial killers, this one uses different methods every time. All of the victims were killed in public, yet the killer does not show up on any security feed. And each victim has a string of numbers tattooed on their wrist. Hidden in the numbers is a code-and the closer the Naturals come to unraveling the mystery, the more perilous the case becomes.

Bad Blood

by Jennifer Lynn Barnes

Published 1 November 2016

When Cassie Hobbes joined the FBI's Naturals program, she had one goal: uncover the truth about her mother's murder. But now, everything Cassie thought she knew about what happened that night has been called into question. Her mother is alive, and the people holding her captive are more powerful -- and dangerous -- than anything the Naturals have faced so far. As Cassie and the team work to uncover the secrets of a group that has been killing in secret for generations, they find themselves racing a ticking clock. New victims. New betrayals. New secrets.

When the bodies begin piling up, it soon becomes apparent that this time, the Naturals aren't just hunting serial killers.

They're being hunted.


Book 4.5

Twelve

by Jennifer Lynn Barnes

Published 29 November 2017

Cassie Hobbes has been working with the FBI since she was a teenager. Now twenty-three years old, she and her fellow Naturals have taken over running the program that taught them everything they know. As a unit, they're responsible for identifying new Naturals—and solving particularly impossible cases. When their latest case brings back a ghost from their past, Cassie and the other Naturals find themselves racing against the clock—and reliving their own childhood traumas.

In a small, coastal town in Maine, there has been a rash of teen suicides—or at least, that's what the police believe. Mackenzie McBride, age twelve, thinks differently. Desperate to make herself heard, she stands at the top of a lighthouse, threatening to jump... unless the FBI agents who rescued her from a kidnapper at age six come to hear her out.

Enter the Naturals. It doesn't take Cassie long to realize that Mackenzie isn't bluffing: she truly is convinced that the suicides are murder, and she really will jump if she can't get the FBI to believe her. To the outside world, Mackenzie is nothing more than a traumatized child. But so was Cassie, once upon a time. So were Michael, Dean, Sloane, Lia, and Celine. With a storm rolling in off the ocean and Mackenzie's position becoming more precarious by the moment, the Naturals have very little time to get to the truth about the deaths—and about twelve-year-old Mackenzie McBride.
