Before I Die, the interior monologue of a 16 year-old girl dying of leukemia is haunting, compelling, and at places downright beautiful. Written with an adolescent market in mind, some plot features may be a little starry eyed for the adult reader, but overall the book is a worthwhile read--impossible to put down once begun or to finish without a tear. The younger brother, age not given but apparently in the 9-11 range, is almost perfect, with his love and fear for his sister warring with his own needs for attention.
