I believe that this should be categorized as Young Adult fiction. It examines both sides, the giving and receiving, of a donor liver, but it is more about a woman staying with an abusive husband for reasons an outsider wouldn't understand, like really having no place to go and no means of support, of losing custody of your children because he's too powerful and rich, like feeling that it's your own fault, that he will change. The book is told through the eyes of a teenaged organ transplant recipient and also in third person about her abused mother and the donor's mother.
This book might try to cover too much, like the teenaged liver recipient trying to fit in in high school, her feelings about her abusive father, the mother's emotions, the mother of the liver donor's emotions, but it is a good book for young adults.
