This is an UPDATE: This book is nothing short of amazing. Thrilling, edge-of-your-seat action keeps you swiping the pages of your Kindle till you get to the end, then, you just want more of Tyler. He is a former Special Ops guy and keeps you riveted with his ability and tactics to get out of tough situations, and on top of that, it's all pretty believable. When you've finished this book, you'll immediately want to move on to the second book. FULL DISCLOSURE, I read this book as an ARC over a year ago, and I enjoyed the story, characters, and action so much that I continued through the series. I came back to update this review because after reading more of Tyler and the spinoff stories I wanted to impress upon anyone reading this review that his is nothing short of a MUST READ series. Starting here will give you some good background, but it is absolutely not necessary...the backstory and character development in EACH of the books is phenomenal, so you can pick up anywhere. But, you'll certainly want to read them ALL. One click now, you won't be disappointed.
