From the primeval rain forest comes an uncontrolled substance never intended for consumption by the civilized mind.... 

To the warrior shamans of the Venezuelan forest people, the drug is a sacred substance: part pain, part pleasure, all power. Skullflush is pure psychic whiplash...an exhilarating gateway to an advanced consciousness beyond time and species.  

Deep in the Amazon, the primitive tribe has kept its secret safe from civilization - until a rising drug lord ends up with a stolen six-kilo stash and begins to peddle his prize in the nightclubs of Florida.  

Tampa’s thrill seekers are eager to sample the pale green powder. But generations of urbanized decadence have left them jaded, shallow, and weak...too weak to handle the drug’s mystic high. The ancient rain-forest chemistry warps bone, muscle, and sinew in their city-soft bodies, setting free the ferocious power of man’s basic nature.  

On the rebound from a life in ruins, Justin Gray is the sole witness who can connect the fearsome power of skullflush with the carnage left in its wake. A marked man, with a new love and an unlikely ally from the heart of the rain forest, he's forced to learn the ways of the urban jungle, where everyone is both hunter and hunted.
