Great book...keeps you on the edge of your seat!
Cussler at his best. Action packed and just the right amount of romance, Dirk Pitt style
From back cover:
1954. Vixen 03 is down. The plane, bound for the Pacific carrying thirty-six Doomsday bombs - canisters armed with quick-death germs of unbelievable potency - vanishes. Vixen has in fact crashed into an ice-covered lake in Colorado.
1988, Dirk Pitt, who heroically raised the Titanic, discovers the wreckage of Vixen 03. But two deadly cannisters are missing. They are in the hands of a terrorist group!
