The Pharaoh's Mask
Another steampunk, alternative history adventure of the Charlemagne Griffon Chronicles.
Charlemagne Griffon, Charlie to his friends, loses his commission, gets kicked out of the Army and has a bounty put on his head and that's just the start of his troubles. He and his man, Etherton, go on the run ending up in Cairo where they set themselves up as adventurers and guards for hire.
An expedition searching for the lost tomb of Amun at Jebel Barkal in Somalia takes him on as the head of security, but all is not what it seems. A prophecy in the Book of the Dead foretells the return of Amun to the mortal world bringing enslavement and death to mankind. With more twists and turns than the Nile itself this story will keep you awake until you finish it.
