The Realm

The Realm: A Novel The area in space known as The Realm contains thousands of galaxies. Nowhere else in the universe is the concentration of galaxies as high. But the thick, constant cloud cover on Maripol, a planet in the huge Virgo Cluster in The Realm, prevents its residents from seeing the wondrous sight of trillions of stars. There, 60 million light-years from Earth, survivors of a lost starship struggle to maintain their civilization.
But one of them, Erin Jones, is about to begin an adventure that will take her those 60 million light-years to Earth and back. And along the way, with the help of her AI friends Great Gramps and Maxwell, she will save her civilization from the "other AIs" and see The Realm in all its magnificence. The Realm, though new in characters and story, uses much of the extrapolated science, with some new ideas, taken from my universe's Future Chron and Forgotten Earth. For more information, see the author's website.
