This isn't a normal thriller type book, the beginning of the book has you instantly questioning if Rob is who he says he or if he has been swapped with his 'doppelganger' the added confusion of a previous brain injury with the main character adds a lot to this story.
Overall it is a good read, although I would have liked to see more of a back story between the couple as it does instantly make you question who Rob really is. I feel a bit of history between the couple would have helped build the story more, although this may happen later on in the story it is not apparent within the first four chapters.
I would definitely still like to the read the rest of the book to find out what happens with the main character and Rob and whether he is who he says he is or not.
