How I Got the Book: Bought


“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 tape. 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.

Meanwhile, Cassie is dealing with an equally dangerous and much more painful mystery. For the first time in years, there’s been a break in her mother’s case. As personal issues and tensions between the team mount, Cassie and the Naturals will be faced with impossible odds—and impossible choices. ”

Best YA Thriller Series

The Naturals seems to be a slighly underrated YA series, and I’m baffled why. Each book has had its own flavor and Naturals team member being focused on. Plus, they amp up the suspense and crime solving each time.

All In was another great sequel. The perfectly book is set in the seedy, bright-light city of Las Vegas.

A few thoughts:

The love triangle is over. And I’m so thankful. There is no wavering; the decision has been made, and it’s over. Thank you, Jennifer Lynn Barnes! More books should follow this format.

Each book looks deeper into a character’s history. In this book, we get a closer look at Sloane, the statistic whiz known for her lovable non-sequitur dialogue. We find out so much about how Sloane came to be in the Naturals program and why she is the way she is.

The suspense and crime solving is back with those meddling kids! The Naturals are FINALLY being taken seriously and are working on live cases. Seeing them in action was just as fun as past books, and with higher stakes than ever before.

While I felt compelled to read, All In lost some of the past books’ cannot-put-this-down-ness. It might just be me on this one, but the story lacked an immediacy to read. It was easy to pick up and put down for me, where as the other books I could not force myself to stop reading.

I think there’s only one more book left, and there has been some fantastic build up to it in All In. I love how something from book 2 and book 3 have been working together to finally be revealed in book 4. Masterful.

I will wait quite impatiently until it comes out next year!


Barnes has done it again. She’s created an crazy complicated crime that unravels slowly, adding tension and intrigue the whole book. All In is a great addition to The Naturals books, and I highly recommend it to all thriller/mystery fans!

About Lisa Parkin

I'm a hardcore lover of young adult fiction and have been reviewing books since 2011. Other interests include Downton Abbey, heat lightning storms, Harry Potter land and (begrudingly) one orange tabby.
  • That’s so funny that you felt the can’t-put-down-ness was less than the previous titles in the series, because I felt more sucked-in than ever before. I felt like there were some really interesting reveals for Lia and I was a huge fan of the focus on Sloane. Not to mention the emotional upheaval with Cassie. I completely agree about the love triangle being over. That was one of my few hang-ups about the series, and I think is part of why I enjoyed this one more. Also, Vegas. I loved that they were in Vegas! Coupled with the ending that was like a complete “Wait. Whaaaaaat?” for me, made this one my favorite of the series so far! Good luck waiting for book 4, you definitely have company!
