All your unanswered questions are resolved in this shocking installment of the Naturals series - now with the addition of the novella Naturals, Twelve, published for the first time in print!

When Cassie Hobbes joined the FBI's Naturals program, she had one goal: to uncover the truth about her mother's murder. But now, everything she thought she knew about that night is in question. Her mother is alive, and the people holding her hostage are more powerful - and dangerous - than anything the Naturals team has faced before.

As Cassie and her team work to uncover the secrets of a group that has been killing in secret for generations, they find themselves racing against the clock. As the bodies begin to pile up, it becomes clear that this time the Naturals aren't just hunting serial killers. They're the ones being hunted.

Born smart. Born tough. Born FBI.

“The Naturals series is Criminal Minds for the YA world, and I loved every single page” - Ally Carter, New York Times bestselling author.
