Free Fire

This is another good entry in the Joe Pickett series. In this one, Joe Pickett goes into Yellowstone National Park to investigate a mass murderer. It proves to be no easy task.
We get an interesting story with a good mystery and the typical C.J. Box twists. We get cold-blooded killers, some odd-ball characters, slimy politicians, dirty cops, corporate intrigue, danger, and no little violence. In addition to all that, Yellowstone Park itself becomes a character in this story. (This story says to me that C.J. Box really really likes Yellowstone.)
