Query: Who wrote this book?

I can't believe that John Sandford actually was the author of this book. It doesn't read like a Sandford. I would definately reccommend skipping it. It offered nothing to the Prey series. It never got moving, it introduced numerous redundant characters and went into the last few pages before introducing the villian. Readers weren't allowed to become acquainted with the villian at all. Didn't follow the rules of a good mystery. Extremely boring.
