I read pretty much anything, from fantasy (City of Stairs by Robert Jackson Bennett) to romance (Bared to You by Sylvia Day) to classics (Heart of Darkness by Joseph Conrad). The only genres I don't read are self-help and comic books/graphic novels.
This was a very interesting book, a little bit gruesome, so if you're squeamish or a young person, this isn't the book for you. The author gained the trust of a number of serial killers and so got a very detailed account of a number of murders of men, women, and children. I love true crime and so found this fascinating, but it isn't for everyone.
