The swamp belongs to them. Humans are only prey. Deep in the overgrown swamps of Florida, where humans rarely dare to enter, lives a race of creatures long thought to be only the stuff of legend. They walk upright but are stronger, taller and more brutal than any man. And when a small boat of tourists, held captive by a fleeing criminal, accidentally kills one of the swamp dwellers' young, the creatures are filled with a terrifyingly human emotion-a merciless lust for vengeance that will paint the trees red with blood.
