My Sisters Keeper - Jodi Picoult.

I thought this book review would be the opposite to my last one. My last one was a very sad one and I was hoping this would be a happy one; however I was wrong, it was also a sad one. On the other hand there was a very positive part for the family, their bond with one another. One girl thought her life was just for helping someone else and that she wasn't meant to have a normal life like everyone else. Even though she had a normal life she was still born to help someone's life be saved. But in the end did she actually save somebody's life or did she just help and it never worked in the end?
