My Sister's Keeper: a novel By Jodi Picoult

In her highly acclaimed novel My Sister's Keeper, bestselling author Jodi Picoult tells the provocative story of one family's struggle for survival at all costs. Anna is not sick, but she might as well be. By age thirteen, she has undergone countless surgeries, transfusions, and shots so that her older sister, Kate, can fight the leukemia that has plagued her since childhood. The product of preimplantation genetic diagnosis, Anna was conceived as a bone marrow match for Kate—a life and a role she has never challenged... until now. Like most teenagers, Anna is beginning to question who she truly is. But unlike most teenagers, she has always been defined in terms of her sister. So, Anna makes a decision that for most would be unthinkable—a decision that will tear her family apart and possibly have fatal consequences for the sister she loves.
