The powers that be have decided that the Apocalypse will begin on a Saturday night. But Crawley and Aziraphale, the demon and the angel who were assigned to Earth, have no desire to see their creature comforts blown to bits. So they must destroy the most powerful person on Earth--if they can get through the Four Motorcyclists of the Apocalypse first. "Hilariously naughty".--Kirkus Reviews.
