I have a (slight) book addiction. And most of the time I don't do anything to curb or contain it. I think it's the promise of a better me that draws me in. Here are the sections in my home library:
fitness (of course)
organization and de-cluttering (because I am by nature a slob who married an ultra-neat person)
beauty and fashion (because I need girl lessons!)
home decorating (ditto!)
quilting (I used to quilt a little bit and I am a book learner)
self-improvement of various kinds
fiction (small section)
I used to read fiction more, but don't like that "I MUST finish this book" feeling that I get when I'm about 2/3 of the way through. However, I did finish a really good book yesterday: The Memory Keeper's Daughter, by Kim Edwards. It's not a lighthearted summer read (for that, check out any of the Shopaholic books -- a guilty pleasure, for sure!) but thought provoking and compelling.
And I just started Free Gift With Purchase: My Improbable Career in Magazines and Makeup by Jean Godfrey-June. It's fun. It's light. And it's perfect for the end of summer.
