Written by Jodi Picoult. I bought this book a few days ago and was unable to put it down. It is the story of a family with a daughter that has a rare form of leukemia. And a younger daughter that was genetically designed to be a perfect donor match. It tells the story spanned through 13 years and from everyone's point of view. It sucked me in from the beginning. I finished it this morning, crying. It's wondefully written, and makes you think, "what would I do in that situation?" I highly recommend it, but have a couple packs of Kleenex available at all times. I found it at Target for $11.99.
