Probably the worst Cussler book I'll ever read, from what I hear, and so far it is the worst I've read. The plot is awesome and very detailed but the story moves slow and a few times he even insults the readers intelligence. I know it was writen in 1999 but I know what a Hovercraft is Clive and I knew then too...shesh! I didn't find the ending that exciting either and I would suggest that people only read this book if they are fans of Cussler. I would never let a new reader have this as thier first ever Cussler read. Overall it was ok but there's just too much garbage that didn't need to be in here. It actually would have been an awesome book if it was say 150-200 pages shorter.
