Sabotage, murder, cover-ups. Just another day on the Moon.

After 35 years of living on the Moon, cranky old oxygen farmer Millennium Harrison has stumbled onto a hidden facility in the shadows of the Slayton Ridge Exclusion Zone with a radiation leak and a deadly secret. Mil's discovery leads to the death of a young astronaut, sabotage, murder, and cover-ups that may go all the way to the Chief Administrator of the space agency. Unfortunately, she happens to be Mil's estranged daughter, busy trying to secure her own legacy—the first international mission to Mars.

With time ticking down to a limited launch window, enemies, friends, and even family may do anything to ensure the truth doesn't come out. Or will history finally catch up with a deadly scheme that has the potential to destroy the moon and eradicate all life on Earth? It seems the planet's only hope is a cantankerous guy who never really liked those people in the first place.
