Em and Finn are being tortured in a prison by “the doctor” and this is not the first time. They have travelled back in time, on many occasions to try and change the course of events that has led the world down a negative path. This might be their last trip back and they know they must kill a key player, the person responsible for the time machine, in order to right the terrible wrongs. If they are able to accomplish their task, their lives as they know it will change, their personality that has been so dramatically altered because of their trials and her relationship with Finn may never happen.

Too many hints in a review will damage the reader’s experience. This is one of the best time travel books I have read in a very long time. The story jumps from present day Em to her past teenage years as Miranda. Details are eeked out bit by bit so the reader can put the puzzle together of the series of events that led Em and Finn on this mission. This book should be a huge hit for teens and I expect it to make several ‘best of’ lists.  This is the first in a planned series.  Highly recommend!
