I LOVED this book. I couldn’t put it down…literally. Walker’s writing is strong and intense. His story was filled with suspense but not over dramatic. Revolving around a highly flawed main character and set in Chicago, among other locales, this book is a stand-alone thriller, but it has spurred me on to read all of the other book Walker has written, series or not. The relationship between the boy and the main character is highly believable. It never gets too sappy or mushy. And the ending is strong. I was hoping against hope that Walker wouldn’t ruin the ending as many authors do by taking the “Hollywood” way out. But, the ending is as strong as the first pages. I’ve met Mr. Walker on a few occasions and he is, on the surface, a mild, unassuming man. But, he sure writes a WILD, FAST-PACED thriller. A GREAT thriller!
