Out of Africa comes a package for Samuel Walker, a young Christian scientist. The package includes a plea for help from longtime missionary friend Clyde Derrington. Samuel travels to Africa to help his friend, whose work is being hindered by "something." In his investigation, Samuel finds evidence of a creature that has the natives frightened—but what is it? A dinosaur? A dragon? Perhaps the Leviathan of Job 41? Who are the mysterious people determined to keep him from finding out? What are they trying to protect—their religion and way of life or the Leviathan?
