Darla N. Warner

A marine biologist, a dolphin trainer, a research scientist, and a local sheriff try to hunt down a large sea monster, a shark/octopus hybrid, that is devouring swimmers and fishermen off a south Florida coast.

A medium has a vision of a hit-man killing his target. The vision comes true, and the same hit-man is assigned to kill her. Her drunk father/manager doesn't believe she has the gift, and a curious journalist tries to protect her.
