Atlantis

Atlantis, David Gibbons

Just a fun novel about the greatest deep-sea diver in the world with millions of dollars of non-profit save the seas/save the world type assets who gets intertwined into an evil empire run by the father of this cute archeologist he hooks up with. . . .anyway, he flies all these jets, the good guys win and discover a whole new civilization while he and the chick hook up.  Same old same old, but fun nonetheless!

(Kind of like "Top Gun" for the sea)
