Travel to Egypt and join a team of archaeologists who have uncovered what evidence reveals is the lost fourth pyramid of Giza. Djedefre, son of the great Khufu, would stamp his supremacy by erecting the highest pyramid ever built, towering some 60 feet above Khufu's Great Pyramid of Giza. This is the story of the most powerful, prolific, and arguably, the most cruel and debauched of all Egypt's dynasties.
