As an author, I like to read books similar to ones I'm writing. Right now, I'm working on something that prompted me to pick up "Hope". It's a fascinating read. The main character of Gabriel Jones is compelling, and his outlook and perceptions are astonishing. If certain taboo subjects (prostitution, explicit detail of pornography, etc.) do not disturb you, then check this out.
