Mutation, by Robin Cook, is an intense fictional thriller. This book really kept me reading and always left me to think of what was going to happen next. A genius scientist, Victor, had a mutated baby(Vj). Vj grew up to be very smart and wanted to be like his father. All the things Victor was working on, Vj was also. Vj tried to get all the acceptance he could from his parents and finally everything Victor was working on, backfired at him.There were many different themes in this book, but the one that stuck out to me was the parent and child relationships. This theme made the book very suspensful and I was always waiting for something to happen between Victor and his son Vj, or Vj and his mother Martha. This book really points out how the acceptance from your parents helps and when they dont accept, it all might ruin everything.
