I'm having a tough time putting this one down...

"... I was born for a very specific purpose. I wasn't the result of a cheap bottle of wine or a full moon or the heat of the moment. I was born because a scientist managed to hook up my mother's eggs and my father's sperm to create a specific combination of precious genetic material. In fact, when Jesse told me how babies get made and I, the great disbeliever, decided to ask my parents the truth, I got more than I bargained for. They sat me down and told me all the usual stuff, of course - but they also explained that they chose little embryonic me, specifically, because I could save my sister, Kate. 'We loved you even more,' my mother made sure to say, 'because we knew what exactly we were getting.' ... See unlike the rest of the free world, I didn't get here by accident. And if your parents have you for a reason, then that reason better exist. Because once it's gone, so are you."

The book is My Sister's Keeper by Jodi Picoult and it is a story about a girl named Anna that has undergone surgeries all of her life to help her sister, Kate, fight leukemia. Now Kate's kidneys are failing and it is assumed that Anna will donate, so she sues her parents for the right to her own body.

I am only a hundred pages in to it, but it's a great read so far!
