Central Heat (Hardcover) (ISBN-13: 9781736288610)

When aliens remove the sun, life survives in military bunkers under the earth and in lunar bases. Underground America devolves into a religious-military dictatorship.

Jonathan Holroyd escapes to the surface and finds a new world warmed by an artificial sun, and only slightly more freedom than in the dying world he left behind. He rises to a position of power.

But now the aliens are coming back.
