As I do not read much science fiction I could not relate to this book as a s.f. reader would. I remember some of the books but not enough. I thought that the young girl was living in her own dream world and did not want to face the fact that she and her sister were hit by a car when crossing a street. Her twin sister was killed and she was left with a very damaged leg. To cope she thinks her mother is a witch and had tried to kill them or not. If you like science fiction you will love the many books read by the people in this book!
