Book review, as posted on my personal journal at http://freefloat.livejournal.com/194948.html (you're all invited):
"It's written in a very easy to follow, fast-paced, exciting style, which just grabbed me and threatened to drown me in the story that very night. The book came with me to work and back for two days - I couldn't put it down - good thing I've developed the ability to read while walking down the street, navigating through subway stations, etc. This book is a definite 5 out of 5.
Because this copy of the book is a Travel Bug, it will be making its way into a Geocache very soon, but your local library may have a copy on its shelves. If you like action-adventures with a theme of puzzle-solving, you would enjoy this book!"
