This year, I also discovered the beauty of autobiographies with with Rob Lowe's and Andre Agassi's memoirs. I definitely like reading first hand accounts rather than biographies that someone else has written. You get a much more personal feel when it's written by the subject himself. Reviews of Stories I Only Tell My Friends and Open.
I read less Chick Lit this year than in the past, but I still got some in. Reviews of While We're Far Apart, Sisterhood Everlasting, and Where We Belong.
I also got sucked into the Hunger Games trilogy, which was so, so good.
My absolute favorite book of the year was 11/22/63 by Stephen King (review). I've never read a book like it, but I desperately hope that he writes more books of the non-horror genre so I can read them!
And the award for my least-favorite book of the year goes to Best Friends Forever by Jennifer Weiner. I have loved some of her books in the past, but the two I read this year weren't nearly as good. Or maybe it's just my tastes changing. Best Friends Forever was particularly disappointing. I actually was miserable reading it, but I was determined to finish it! My advice-- don't pick it up unless you want to read an uber-cheesy story with cliche characters and no real resolution.
