The Number of the Beast » (Reissue)

A science fiction pioneer, Robert A. Heinlein wrote popular stories that doubled as vessels for his political and cultural observations. In classics such as Stranger in a Strange Land and Starship Troopers, Heinlein blended suspenseful adventure with (sometimes controversial) visions of alternate worlds.

When two male and two female supremely sensual, unspeakably cerebral humans find themselves under attack from aliens who want their awesome quantum breakthrough, they take to the skies — and zoom into the cosmos on a rocket roller coaster ride of adventure and danger, ecstasy and peril.
