Ex-cop Henry Shore has been Chief Park Ranger at Crater Lake National Park for eight years and he likes his park and his life the way it’s been. Safe. Tranquil. Predictable. But he’s about to be tested in so many ways. First the earthquakes begin…people begin to go missing…then there’s some mysterious water creature that’s taken up residence in the caves below Crater Lake and it’s not only growing in size, it’s aggressive and cunning…and very hungry.
All Patrick Flint wants is a peaceful getaway in the Wyoming mountains for his rare days off. He’s grown weary of the bicentennial celebrations, the angry families of patients, the rash of campers coming down from the mountains high on speed, and the midnight call-outs to cover for the town veterinarian. When his wife Susanne balks at the trip just as they’re walking out the door—leaving him to go it alone with his lovestruck teenage daughter Trish and eager-but-adolescent son Perry—Patrick is wounded but determined, despite the news of a murderer escaping custody on the other side of the mountains.
