Christian and Anna are brother and sister, children to the famous paleontologist Dr. Murphy. When he can't make an assignment to take photos of a newly discovered T. Rex, the children are sent in his place. But are the people they're staying with really who they say they are? Who's stealing equipment? The scientists they're working with are evolutionists, and Christian and Anna are determined to see the evidence support their creationist views in the end. 208 pages, softcover.
