THE RANGER by James Patterson & Andrew Bourelle has an interesting story line with lots of twists and turns. My first guess as to who the killer was came about 1/2 way through and turned out to be correct, but because of the way the story line played out, I was doubting that choice near the end. That's the good news. The downside of this book for me was the primary character, Texas Ranger Rory Yates. Basically, the character development was not up to Patterson's usual stuff. The Ranger is obviously a competent lawman in terms of results and can shoot the lights out with blinding speed from a standing draw. But throughout the story he is way too mercurial, makes many poor choices, jumps to a conclusion about who the killer is way early and won't let it go for emotional reasons, and generally over-acts out in weird ways throughout. If they continue with this character, I hope Patterson & Bourelle "mature' him up some.
