Mars Colony Chronicles Books in Order

With an alien fleet approaching Mars, archaeologist Ozzy accepts a criminal leader's mission to recover an ancient weapon. His unusual ancestry may let him activate it, but saving humanity could require sacrificing his own life.

Ozzy searches for a missing component that could turn Mars's ancient defense into a weapon against its invaders. Meanwhile, an authoritarian leader wants control of the technology, making humanity's own politics as dangerous as the alien threat.

After aliens devastate Earth, a deadly plague threatens humanity's remaining refuge on Mars. Black-market archaeologist Ozzy Mack must decipher ancient Martian relics before the disease reaches his daughter and the survivors depending on him.

The final clue to completing an ancient weapon sends Ozzy Mack back to alien-occupied Earth. He must recruit a crew and search archaeological sites before the invaders seize technology that could threaten the entire galaxy.

Returning to Mars after a failed mission, Ozzy warns that humanity must flee an approaching alien armada. Hunted by his own government, he follows one last clue that may reveal a greater purpose for the ancient Ark.
