Book All In — Jennifer Lynn Barnes

Seventeen-year-old Cassie is a natural at reading people, piecing together the tiniest details to know who a person is, and what they want. But it's not a skill she takes seriously until the FBI come knocking - they've begun a classified program that uses exceptional teens to crack infamous cold cases, and they want her to join.

What Cassie doesn't realize is that there's more at risk than a few unsolved homicides. Sent to live with a group of teens whose gifts are as unusual as her own, she quickly realizes no one in the Naturals program is what they seem. Emotion-reader Michael is a wild card - and far too perceptive for Cassie's good. The resident deception-detector is a pathological liar, and the program's perky, blonde statistician is far better with numbers than with people. And then there's Dean - a profiler like Cassie but with a much darker gift.
When a new killer strikes, danger looms close. 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.
Perfect for fans of Criminal Minds and Holly Jackson, Jennifer Lynn Barnes delivers a suspense-ridden psychological thriller with killer appeal, a love triangle to die for, and a gorgeous new design that will stand out on any shelf.
