When aliens decide that Earth's end is the perfect occasion for a meal, the phrase "world-ending event" gains an entirely new, and gastronomic, meaning. "They Came and Ate Us" follows the odd adventures of Elvis, Rex Mundi, and a sentient sprout (yes, you read that right) as they try to prevent Earth from becoming an alien buffet.
Robert Rankin pulls no punches in the absurdity department, doubling down on the elements that made the first book in the series such a hit. With a plot that unfolds like a B-movie script gone haywire, and characters that would make Monty Python proud, this sequel will be right up the alley for SFcrowsnest readers who think that the end of the world is a laughing matter.
