This book is completely ridiculous. I really like the ideas of what happened to Atlantis, but beyond that, the book had its head in the clouds. The author spent pages and pages of each chapter describing technical mumbo-jumbo that was impossible to understand and didn't contribute to the novel. But probably my biggest problem was that the main characters lived to the end! They should have been dead half-way through the book, but apparently disarming a warhead, sinking to the bottom of the ocean, being shot, running out of oxygen, being fired at with missiles, jumping out of flaming helicopters, being attacked by a tiny submarine, and escaping a terrorist prison are all just in a day's work for these people.
