The moon is being dragged from orbit, in book 4 of this science fiction mystery series.

Geology instructor Alex Cave receives an urgent message about an unusual event in Iceland. Giant globules of molten rock are defying the laws of physics by floating up out of an ancient glacier, creating a huge spiral tunnel down into a dormant volcano.

Alex and his friend Okana descend deep into the mountain, seeking answers to the strange phenomenon. They are reluctantly joined by Janice Sloan, a ruthless woman dealing in stolen technology, and John Essex, a millionaire scientist fanatical about conquering outer space and mining the moon. What they discover at the bottom is an alien artifact more powerful than a nuclear weapon.

In book 5, the color of your eyes will determine if you live or die.

Alex had discovered four alien artifacts that seemed designed to destroy all life on Earth. He thought they were locked up in the top-secret facility at Groom Lake, Nevada, but two of the devices have gone missing, and one of them is in orbit over our planet.

John Essex is fanatical about conquering space, and has good intentions when he steals one of the alien devices. He never imagined it would wake an artificial intelligence named Pandora. Her spaceship carries a colony of human slaves, who have been in stasis under the ice for eighty million years. When she detects the signal from one of Alex's devices, she brings the ship to the surface.

Alex is sent a copy of a recording showing the mirrored surface of an alien spacecraft below the ice in northern Iceland. He and his best friend Okana race to the sight and make contact with Seth, the ship's Captain, and Pandora's spokesperson. He informs them Pandora claims ownership of our planet, and has discovered there are people with brown eyes among our species. She will allow some of us to live if we kill everyone with brown eyes, or she will destroy every person on Earth.

In book 6, your DNA and social media postings will determine who will be chosen to survive a coming apocalypse.
