The worst book I ever read was a biography on the late Rolling Stones guitarist Brian Jones. I picked the book up not knowing anything about it or the author. There's not much info on Brian out there so I was stoked to find this book. As I was reading it, I was amazed at the amount of information and quotes the author had about Brian because much of the stuff I had never heard before. As I got a little past the halfway point of the book, the author revealed that she was communicating with Brian in the afterlife. She got most of her inside information from a dead guy. I didn't finish it after I figured out what was going on.
