Great book! Read them in order ;)

The longer you read the dumber it gets. Had to stop. Couldn’t take one dumb coincidence after another.

Kind of fanciful but still exciting and fun to read. The technology is not explained very well which should be expected considering how unlikely it is. Excellent action with lots of bad guys. I can recommend this book.

Once again Clive Cussler has created a riveting suspense action novel about the adventures of Juan Cabrillo and his crew of the Oregon. Loved every minute of it. Couldn't put it down. Sorry it had to end.

Great action laden book. Keeps you in suspense from the first to last page.

I have read several Cussler books, but this was the best....very difficult to put it down. A fantastic read.

This one was particularly good! Get it if you love the exploits of Juan and his crew, and futuristic high tech devices. Very good book, went fast.

That's it; the premise of this book is just plain stupid.

I'll miss du Brul but this is just as worthy.

Every time I read a book that was penned by Clive Cussler I'm never disappointed and Piranha was no different as the adventures of Juan Cabrillo and the Oregon continued with a threat straight out of science fiction but dealt with by military like force. With ups and downs and Cusslers ability to make you not want to put the book down it makes a fast and thrilling read. If you're up for an adventure this is the book for you!
