If you like Hitchhiker’s Guide-type humor, try Terry Pratchett’s Discworld series. I’m now so completely hooked on these books that I’m sure I’ll be spending way more money than I ought so I can eventually own them all. (Yes, I know, I could get them out of the library, but Denis likes them too and I can definitely see reading them again someday.)
I started the first book 3 weeks ago, and now I’m almost done with the fifth. That’s not all that impressive, I suppose, as they’re not terribly difficult reading, but considering most of my “me” time lately has been rehearsing for the musical or practicing horn, it’s not too shabby.
I personally think it’s quite hysterical that Death rides a horse named “Binky”. I’ll never look at Carrie’s pacifier the same way again…
