Outside Cincinnati, Ohio, there is a wasteland that used to be Wright-Patterson Air Force base. Three years ago the aliens invaded there, turning Wright-Pat into a nuclear wasteland, the detritus of a terrible battle. It was no ordinary battle, but a battle with something utterly unworldly, something unhuman and inhuman, a force no man could ever hope to master. . . . Now the aliens have returned -- their agents walk among us, indistinguishable from you or I. The Aliens have landed. And nothing in the world will ever be the same.
