The Mystery, Crime, and Thriller Group discussion

My latest novel, Devil in the Hole, loosely based on a true crime, a forty year old New Jersey murder case in which John List murdered his entire family, wife, three teenage children, mother and dog, and then disappeared, was recently published. It's not a whodunit but a whodunit, as well as a study of how the murders affect those around him and those he meets along his escape route.
If you do read it, I'd love to know what you think.
