Cast Upon a Restless Sea

Fifteen-year-old Karina expects hardships and surprises during her five-month school term at sea aboard the "Star Fin, " a research vessel designed to turn troubled adolescents into responsible adults. Classes in marine biology and advanced scuba diving help her gain confidence and self-control; but nothing prepares her for encounters with moray eels, a dangerous Portuguese man-of-war, deadly sea snakes, and man-eating sharks. When blood-frenzied sharks viciously attack a family of capsized kayakers, Karina's skills and courage are put to the ultimate test.

Her skills are tested even further when Karina and her peers attempt to explore a shipwreck deep in the ocean. After the group is sabotaged and stranded by a fellow classmate, everything that can go wrong, does. Are Karina and her friends strong enough to survive the elements, a sinking ship, and decompression sickness?
