This is the book that was selected for "Omaha Reads" this year. I was kind of embarrassed that I had never read it before and just assumed that I was the only person I knew who had not. It turns out that I wasn't, but this was so incredibly well researched and well written that I will recommend it, even though the murders in it are pretty gruesome, as are some of the details of the killers' lives. The more I read, the more I appreciate a well-crafted story. Even though I knew the gist of the story, I didn't want to put the book down, because I wanted to know what happened next in the narrative.
