This was a great, thought-provoking read. The only thing that kept me from giving it 5 stars was that my logic-oriented brain couldn't wrap my head around some of the supernatural aspects: WHY couldn't they see in color? HOW did he get the memory that turned out to be a future event? I just felt that there were a few loose threads I would have liked tied up more clearly/neatly. I listened to the book, and the reader was good.
