Considered by many readers the best alien invasion novel to date, FOOTFALL was called "thought-provoking and exciting" by Library Journal and "the best of its genre" by The New York Times.

An alien craft is approaching Earth. Attempts to communicate go unanswered. The welcoming committee of Americans and Russians at a space station is blasted, its occupants killed or captured. Soon the entire Earth, with special emphasis on the United States, is bombarded by asteroids, destroying dams, highways, and infrastructure. The message to humans: total surrender or death to all. A giant rock, the "footfall", is launched towards Earth, causing even more damage. The aliens land, determined to conquer or utterly eliminate the human race. Understanding a truly "alien" culture and learning how to fight such an overwhelming power make FOOTFALL stand out as an outstanding and truly original novel.
