A Lit Match in Orbit: The Returning, Science Fiction Book, Hudkins Publishing

At a point soon, a catastrophe has made a portion of the Earth uninhabitable. Before the event, many humans were evacuated to the space stations and began living up there. By the time the event happened, there was already a separate and sustainable society of space stations orbiting the planet.

 The catastrophe did not destroy Earth, and some inhabitable areas remained. A new government is created on Earth, separate from the laws and government of the orbiters. Laws include the fact that it is illegal for any orbiters to return to Earth unless they are married to someone on the planet.

Despite the fact that the relationships are strained 200 years later, they are peaceful, and the lines of communication remain open. Finding a terrestrial (Earth person) to marry online is one legal ticket home. This story is about one girl who finds true love and is allowed to return to Earth.
