What Picoult does best is pose a moral dilemma and craft a story around it. I like many of her books, but this one is my favorite. In it, 13-year-old Anna is not sick but she might as well be. She has undergone countless medical procedures so that her sister Kate can counter the leukemia she has been fighting since childhood. In fact, Anna was conceived to provide a bone marrow transplant for Kate. But Anna is beginning to question her role, and she sues her parents for the right to make her own medical decisions. The book does more than just question the legitimacy of giving birth to one child to save another. It also raises the specter of how far it is okay for parents to go to save a child, and if the child has the right to question the parents’ decisions. What happens to the healthy child or children when the family deals with such an illness? My Sister’s Keeper addresses these questions and more with an unexpected twist at the end you won’t see coming.
