My sister's keeper

I just finished reading My sister's keeper by Jodi Picoult..its a pretty sad book! The ending was horrible! I was completely shattered at the ending, the worst ending possible! So the story is that Anna, a 13 year old girl wants to sue her parents because they want her to donate her kidney to her sister who has leukimia(blood cancer). She hires a lawsuit for it and there's a trial and stuff too...but really horrible ending! I couldn't believe my eyes! Here's the front cover of the book...
