In the year 2025, time travel has become the latest rage. Nathan and his family are looking forward to visiting ancient Alexandria, but something goes terribly wrong during the transfer back in time. After Nathan lands alone near the palace of Tutankhamun, he soon realizes that unless he can convince the captain of the guards that he is not a tomb robber, a painful death awaits him.

Eventually Nathan is introduced to the young king and becomes a high-ranking member of Tut's court, where he learns about the life and politics of the ancient Egyptian monarch. Assigned to watch for anything that might harm the king, Nathan is devastated when he witnesses a horrifying accident that endangers the life of the boy-king. Meanwhile, as his family tries to rescue Nathan and bring him back to the present, the threat of a major time paradox emerges.

Nathan, accompanied by his sister, Lindsey, must return once more to the tomb of King Tut-a dark world filled with coffins and the threat of curses and magic spells-in a lastditch effort to prevent the destruction of their timeline. But have they arrived in time?
