My Sister's Keeper

Couldn't put this one down. Stem cell research, genetically designed babies, leukemia, and a family dealing with the trauma of life with a very ill family member. What would it be like to be the youngest child in a family where you had been planned, no, designed specifically to provide stem cells to an older sibling with cancer? Maybe you'd be proud to be able to help that way. But then, when the sibling has a relapse, and now they wanted bone marrow - okay, sure, of course you'd be willing to share. In five more years when the sibling relapses, has kidney failure and is on dialysis for 4 years, when your mom says you need to give your sister one of your kidneys... and you aren't given a choice in the matter... now what do you do? Because you love your sister and don't want her to die, but the doctors think she probably won't survive the operation anyway, do you give up your kidney? Or do you fight to keep it? Because either way, your sister is probably going to die.
