Eye of the Predator

Erik Simpson is a brilliant young zoologist who has no memory of his life before the age of sixteen. Trained by his aging foster father, a world renowned zoologist, Erik astounds his colleagues with his insights into animal behavior. 
As his thirtieth birthday approaches, Erik has a recurring dream of stumbling through the Amazon jungle, hunted by a black jaguar. One night he dreams of the hunt, first as an observer, then as the jaguar itself on the prowl in California's High Sierras where he comes upon campers and mauls them in a savage frenzy. 
The next day he receives a call from the National Park Service asking for assistance investigating a bizarre animal attack. When he goes to the camp site, he recognizes it from his dream and tells the authorities that it was a jaguar, and shows them precisely how it happened. 
His quest for the truth leads him into a murky world of magical plants and ancient shamanic rituals that ultimately bring him face to face with the enigmatic mystery of his past.
