If you don't have trouble putting this book down, there's a problem! It gripped me from the fly leaf! It's a good old-fashioned thriller. A man goes on a journey of self discovery because he's lost his memory while a disaster looms. I beleive the book spans only a very short period of time and yet it keeps you literally on the edge of your seat! I read the book and then listened to it on tape with my husband and I think it is equally entertaining either way.
