"You ever hunt werewolf, Whitney?" It is 1903 and that startling question is only one of many posed to young zoologist Gerard Whitney by eccentric Oklahoma cattle rancher Harold B. Tucker. When hired by Tucker he expects only to study wildlife on the ranch, but instead finds himself caught up in Tucker's true passion, searching the world for legendary creatures. And the thing Tucker wants most? To find a living dinosaur! As they embark on one wild and dangerous adventure after another, Whitney is sure Tucker will never succeed. But what they eventually discover exceeds both men's wildest dreams - and nightmares.
