I picked up a couple of books last week. Thanks so much for your suggestions.
One is The Girl with the Dragon Tattoo. My book club is reading it and we meet next week, so I better get to reading.
The one that I have actually started and don't want to put down is One and the Same that Laura C. recommended. WOW. This is an eye opener for anyone with direct relation to twins, whether you are a twin, have twins, or just are friends of twins. It is written by an identical twin, and even though I'm only on the second chapter, I know this will be one that will stay on my bookshelf to refer to for many more years.
