This was book number six in the FBI Thriller series. Savich and Sherlock are back! This book is about Savich's sister, who we'd briefly heard of before, when her daughter died in a previous book. Also, there's a continuation on the serial killer Tuttles storyline they'd previously introduced in an/some other book(s). Both stories were resolved. I like reading mystery/adventure books in a series, because you get to know the characters involved and see what's going on in their lives. The main problem with all the books in this series is that the characters talk like they're five year olds instead of adults. No one talks like that in real life. It wasn't as bad in this book as in the previous one, where it was just so ridiculous it was annoying. In this one, it was a bit toned down, so perhaps she's getting more practice, but i was able to get into the storyline without that distracting me, and it got a four! I can't wait to read the next book in the series!
