Brett Russell is a hunter of the rarest game. His targets are cryptids, animals denied by science. But they are well known by those living on the edges of civilization, where monsters attack and devour their animals and children and lay ruin to their shantytowns. When a shadowy organization sends Brett to the Congo in search of the legendary dinosaur cryptid Kasai Rex, he will face much more than a terrifying monster from the past. Spinosaurus is a dinosaur thriller packed with intrigue, action and giant prehistoric predators.
