I'm torn between giving this 3 or 4 stars and have chosen 3 only because the author used the word "labyrinth" so many times that it really left me wishing that there were more words to describe such a thing.
That being said, this story is definitely one filled with labryrinths and the basic premise reminded me of the the "Eternal Sunshine of the Spotless Mind", although the overall story is different and in the book, more complicated. It's an amalgamation of multiple genres - part mystery, part sci-fi, part love story, part tale of betrayal, part philosophy - all with a focus on searching for the meaning of existence and individual purpose through memories and dreams and the hope and fear associated with, and/or caused by, them.
Even though I was a bit frustrated that the main character took so long to figure out the main "mystery" behind his "amnesia", I thoroughly enjoyed this book and found Sam Taylor's imagination to be unique and thought provoking.
