For as long as she can remember, Anna has known her purpose in life. She was conceived and raised by her parents to be a perfectly matched donor for her sister Kate, who has leukemia. Simple. How can she say no, when it's a matter of life or death for Kate? But after thirteen years of hospital visits and painful medical procedures, under pressure to donate a kidney, Anna finally rebels. This heartbreaking story of courage and self-sacrifice redefines right and wrong, and prompts the agonising questions: how far would you go to save the life of someone you love? And how much love is enough?
