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.
