I've seen several books recommended that I loved, too. For a different idea, try Jodi Picoult's Handle With Care or Lisa Scottoline's Look Again. Both of these will make you think.
If thinking isn't what you have in mind, try Janet Evanovich's Stephanie Plum series. I don't like Evanovich's other series, but Stephanie is laugh out loud funny.
If you are a thrift store shopper, be on the look out for Anne Tyler books. Digging to America is my favorite one of hers. Also, The Diary by Eileen Goudge is excellent. Those books are both over 5 years old, so you might find them at the Goodwill.
I'll stop now, although I could go on forever. I work part-time in the library so I talk about books with lots of people and pick up reading ideas all the time. I often read a book just because someone suggested it and end up loving it. Stretching my reading box has been good for me.
