Primal: A Prehistoric Thriller (Bick Downs)

Bick Downs and the Society of Cryptozoological Agents are dropped into the lush bamboo forests of Vietnam. They are searching for Gigantopithecus, the largest primate that has ever existed. But what they find deep and entangled amongst the trees is not the reclusive giant that roamed the bamboo forests of Southeast Asia several million years ago. Instead, they find something else entirely. The animal has evolved.
