Khephren has paid dearly for his foolish quest for the Cybel of Orichalus. But he continues, driving Alix, Enak and Titus into the terrible Egyptian desert. He wants to rally the oasis of the god Ammon, his sanctuary and his Mountain of the Dead, convinced that the secret that will save him is hidden there. But it is their destiny to all who will play in the strange necropolis, between mummies, looters and servants of the hidden god. The Mountain of the Dead will never have earned his name so much.
