M31: A Family Romance (Unabridged‪)‬

Dash and Dot—husband and wife; self-professed descendants of aliens from the M31 galaxy—are the world’s most in-demand lecturers on the UFO circuit. They live in a decommissioned church in the middle of America, with a radar dish on its steeple and a spaceship in the sanctuary. Their children have the run of the house when Dash and Dot are away. When a couple of UFO groupies show up looking for the extraterrestrial duo, they find instead a nuclear family—or rather, a family gone nuclear—whose comically discomforting world resembles our own as much as it does another world altogether.
