I'm slowly making my way through Divine Romance by Paramahansa Yogananda. 2 or 3 pages a day so I can absorb each message. And I'm a great fan of Danielle Steel (also, I'm impressed with her outreach with the homeless).
I prefer fiction (horror is my favorite genre) but I also like nonfiction. I even read children books sometimes. The only type of books I do not like are the self-help books, I find them stupid. Sadly though the past years I haven't read a lot, the only books since late 2009 that I read were a few of my childhood books which sadly I lost all in a fire. I had many unread books that I did not get to read because of that fire so I have to build my collection again.
I read all kinds. Fiction (funny) when I have the chance. But lots of regional cooking and a biography on someone I love once in a while.
While at the moment, my teens (on Dec 31st!) Yikes~!!!! love the funny books like Diary of a Wimpy kids and such, but mostly they are into Guinness Book of World Records and Ripley's Believe it or Not books. They are becoming investigative and interested in the world.
I read pretty much anything. I'll read books about new concepts and ideas in my career field, fiction, historical fiction, classic literature, cookbooks, even books on different topics that I find interesting.
