Fin Chasers - Richard Smith - Bog

The sighting of Great Whites in the Gulf of Mexico was more than a rare event, it was an extraordinary event. Now, almost overnight, the vicious attacks started. The deadly encounters occurring from Biloxi all the way down to Tampa. The great whites seemed to be on an unexplainable killing rampage.
A 47 foot U.S. Coast Guard Motor Life Boat and five brave crewmen were assigned the task of finding the cause of the attacks and why the creatures were suddenly appearing in alarming numbers along the beaches of the Gulf Coast.
What these five men discovered was much more sinister than a marauding band of great white sharks - they found something lurking deep in the Gulf that had been lying dormant for half a century - A mindless killer void of thought or compassion - It lie on the sandy bottom and waited to be awakened.
