Query: Excellent introduction to a couple of sick puppies

As I got ready to write my review, I noticed 7 1-star reviews and 4 2-star reviews. Where do they come from? The worse rating this excellent book should get would be a 3-star rating.This is my 2nd solo Blake Crouch story, withRunbeing the first. I thought Run was one of the best books I read in 2011. I came into this story having already meet the two main sick puppies, Orson Thomas and Luther Kite when I readSERIAL UNCUT (Extended Edition)in Oct of 2010. I had planned on reading the Andrew Thomas trilogy and when these books became avilable for free in Dec and I jumped at the chance to get these books.I enjoyed the suspense & terror in Desert Places. Yes, Orson is one vicious killer, and he really messed with his brother's mind during this story. The book if full of gruesome killings, but to me, not quite as bad as I read inTrappedby J.A. Konrath. But I can see why Konarth thought he and Blake would work well together based on Desert Places and Run.
