Captain Nathan Hale Bridger left the Navy years ago. Then, he was offered a once-in-a-lifetime opportunity: to command the world's greatest undersea research ship, the seaQuest DSV. The scientific potential is staggering. But so are the unknown dangers that lurk on the ocean floor...

The Voyage begins!

It began with a terrorist threat to the high-tech underwater resort of SousMer, far beneath the Caribbean....It continued deeper still, in the hypothermal vents at the ocean's bottom, where a strange new breed of sea worm has spawned...It could end in death. For the men and women trapped at SousMer. For Captain Nathan Hale Bridger. And for the entire crew of the seaQuest DSV...

In the unexplored depths of the ocean floor, the ancient creature awoke...Beneath the hull of the U.S.S. Baylark, it rose up and attacked...And aboard the submarine seaQuest, it continues to haunt one of the few living witnesses. Captain Nathan Hale Bridger is not completely convinced by the survivor's wild tale of a sea monster. But seeing is believing...
