The PyraMorians — David Lee Jones

Dr. Brandon Jordan discovers a secret sect of aliens living amongst the Martian colony of New Sardonia. He becomes embroiled within a prophesized war that forces him to become a hero in a fight for, not only his life, but for the existence of humanity itself upon the Red Planet.
Meanwhile, on Earth, more evidence that humanity has been manipulated for millennia by a small band of outcasts from another world comes to light. The plot thickens around a college professor with knowledge of the alien powers of ancient crystals. With his assistant in tow, the scholar becomes a hunted target and is forced to run for his life in hopes of keeping the secret alive long enough for the world to find out.
