Ruby City by Charley Marsh

Ruby City hides secrets thousands of years old. None worth dying for. One worth killing for.

Major Rita King takes her newest crew member to visit the famed Ruby City, a city constructed entirely of red crystal ruled by a Snakeman. Once inside the city gates, they find far more than Rita bargained for. Fantastic fables based on truth and a prisoner held for human sacrifice. Can Rita change the course of Ruby City’s history?

Book Four of the Junkyard Dog series, Ruby City once again calls on Rita King’s brains and courage in an unexpected and richly detailed world.
