All In by Jennifer Lynn Barnes

Jacque's Review:

All In is the third book in the Naturals series.  For those of you who are not familiar with the series, it is a murder mystery series involving 5 teenagers recruited by the FBI for their abilities to profile, read emotions, detect lies, and analyze statistics.  Due to their individual upbringings and unusual childhoods they naturally honed these skills to exceptional levels.  

This time around there is a serial killer on the loose in Las Vegas.  So far he has killed 1 person at a different casino each day starting on January 1st.  The FBI is called in because the casino owners want to put an end to this as quickly and quietly as possible before business plummets.  To top things off, there is a huge professional poker tournament just around the corner that must go on as planned.

The naturals struggle with the case because there doesn't seem to be a common denominator.  Different locations, different methods and no common element between the victims,  The only connection between the cases is a mysterious set of numbers found on the wrists of each victim.  

In addition, there is a breakthrough in Cassie's Mother's murder case.  Some remains were found that are believed to be hers.  Jennifer takes this portion of the story in a direction I don't think anyone would have anticipated.  What was deemed to be solid evidence in the case isn't as solid as it appeared and everything Cassie believed to be true is far from it.  

Sloan, the statistician, eventually discovers a pattern that links each of the cases.  The locations and dates of the murders are tied to a mathematical code or sequence that has been around for hundreds of years.  They just need to discover when and where the next murders will take place in order to catch their UNSUB.

If you enjoy YA and thrillers/mysteries this is definitely the series for you.  I have thoroughly enjoyed every book in this series and have been glued to each detail from start to finish.  I love all of the characters and their unique abilities as well as their individual personalities.  They are all so different, but they complement each other beautifully and have really developed into a family.  

The final book in the series, Bad Blood, was just released last week.  I should receive it from the library within the next few days and can't wait to see how the series will conclude.  If you haven't started the series yet, now would be the perfect time.
