I’ve started a favorite books page. Go there if you are curious to see the kinds of books I like to read for fun. This is only a small sample of my favorites, but it should give you some suggestions.
The initial version of the page lists books by the following authors: Tom Holt, Jasper Fforde, Jason Sheehan, Christopher Moore, Ernest Cline, A. Lee Martinez, and Terry Pratchett. I’ll add a few more when I have time.
Feel free to post your own recommendations in that page’s comments.
