Mutation was a decent book that had me guessing every chapter. Plus the description that is included in the book makes the reader feel like they are in the story. This makes the ending of the book more of a thriller.This book was an easy read and a good book for one of those five hour car rides. The different actions the characters perform intrigue the reader while making them want more. It accomplishes the hard task of turning Frankenstein into an accurate modern tale. Now the modern day reader can relate to the reality of the story better. Even though he may get on the extreme side at times it is all used as a device to make the reader not know what to expect next. This book is great for a short fun read in a month or less. It is not one of those books that could take a half a year to finish. Just a nice pleasurable read.
