A mysterious black sphinx, an ancient secret telling of amazing treasures, and smugglers of ancient artifacts.

All these come together in the most unexpected place that could be imagined, a small city in the American Midwest. What starts out as a simple field trip to a museum turns into an amazing and dangerous international adventure for fifth-grader Robby Reardon and his teacher Mr. Reynolds when they meet a stranger at the Egyptian exhibit. Kidnapped because of information they didn't even know they had on the location of a lost pharoah's tomb, they are brought to Egypt. The pair are 'invited' by the friendly but also threatening Greek antiquities smuggler, Alexander Straticus, to help him complete his lifelong quest of finding the tomb. As the search progresses and Straticus becomes more threatening, all of them begin to realize they have gotten into something much greater and more dangerous they they could have imagined!
