Nonfiction has been my salvation from endless loops of re-reading. The fantasy section of local libraries are crap, "realistic" fiction is further from my life than Mars is, and nobody writes fluffy detective novels anymore. So most of what I read that isn't nonfiction is either rereads or YA and children's books. I know lots of fun books for three-year-olds and very few (novels) for thirty-year-olds.
