When Izzy loses half a leg in a car accident, she goes through all of the usual stages of grief (anger, tears, etc.), but it takes her a while to come to grips with how it will affect her, her family, and her friends. But life does go on and Izzy must find the strength to restart her life, return to school, and rebuild her friendships. With the help of a persistent new friend Rosamunde, she does that and more.
A charming, if somewhat long, novel about rehabilitation. For the most part, it is predictable, but the characters are realistic and believable, and there is a good pay-off at the end. Good entertainment with redeeming qualities. (Apparently the book is frequently assigned in school, which is a shame, but you could be forced to read worse!)
