Dangerous Impulses

The Naturals #5

by Jennifer Lynn Barnes

The Naturals are BACK!  #1 New York Times bestselling author Jennifer Lynn Barnes delivers the highly anticipated new installment in her beloved Naturals series. 

Cassie Hobbes joined the FBI’s Naturals program at seventeen because she had an incredible ability to read people. Since then, Cassie, fellow profiler Dean, emotion‑reader Michael, lie‑detector Lia, and statistical genius Sloane have caught serial killers, outsmarted masterminds, and saved countless lives.

Now, eight months after the most twisted, traumatizing case of their lives and still dealing with the psychological fall-out, the Naturals decide to take on a joyful mission for playing matchmaker. With Christmas fast approaching, how hard could it be for an emotion‑reader, a deception detector, two profilers, and a statistician armed with a wealth of data on romantic relationships to secure a happily ever after for two people who are already very obviously in love?

Turns out…very. Because to bring their FBI mentors back together, the Naturals will first have to solve the mystery of why Special Agent Veronica Sterling can’t let herself have the very thing she wants the most. Profiling a profiler is tricky business, and it soon becomes clear that to solve this mystery, the Naturals need to uncover the past. Add in a puzzling series of interconnected crime scenes, an UNSUB with a fondness for snow, and a cold case on the verge of heating up, and it’s shaping up to be a killer Christmas.

Genres: Mystery, Mystery Thriller, Thriller, Young Adult, Romance, Contemporary, Fantasy

About the author

Jennifer Lynn Barnes (who mostly goes by Jen) was born in Tulsa, Oklahoma. She has been, in turn, a competitive cheerleader, a volleyball player, a dancer, a debutante, a primate cognition researcher, a teen model, a comic book geek, and a lemur aficionado. She's been writing for as long as she can remember, finished her first full book (which she now refers to as a "practice book" and which none of you will ever see) when she was still in high school, and then wrote Golden the summer after her freshman year in college, when she was nineteen.

Jen graduated high school in 2002, and from Yale University with a degree in cognitive science (the study of the brain and thought) in May of 2006. She'll be spending the 2006-2007 school year abroad, doing autism research at the University of Cambridge in the United Kingdom.

who's going to tell jennifer lynn barnes that it's okay to end a series

[Salma [inactive]]

I loved reading this series, but adding more books to a series always scares me, because it sometimes feels like a money grab. Pretty sure that was the case with TIG. Hope it's not the same case for this one as well 😭 (Also, please let Michael be with another girl, and not Lia)
