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 - and so Anna makes a decision that for most would be unthinkable… a decision that will tear her family apart and have perhaps fatal consequences for the sister she loves. My Sister's Keeper examines what it means to be a good parent, a good sister, a good person. Is it morally correct to do whatever it takes to save a child's life… even if that means infringing upon the rights of another? Is it worth trying to discover who you really are, if that quest makes you like yourself less?
