I give this book five stars because I had the craving for mystery and puzzles and I got just that. My favorite character is Christopher Rowe. He's the fun one who likes to explore new things and find new puzzles. I recommend this book to anyone that is into solving things and finding mysteries to be revealed. It’s an adventurous, heart racing, page turning novel. If you get a chance to read it, I think you would really enjoy this novel as much as I did.
