Query: Excellent, fast paced, well written adventure!

At first glance I thought that this was going to be a sci-fi type book, and I wasn't really interested. However, I soon found that I couldn't put it down. Excellent characters, writing, and description. Action well balanced with dialogue; the book came alive -- I couldn't put it down. I highly recomend it,
