Ender's Game
Card, Orson Scott. Ender's Game. New York: Tor, 1985.
According to Anatomy of Wonder 4, ENTRY 4-92, EG is an expansion of 1978 novelette; it is also the first of the Ender's series, followed by Speaker for the Dead (1986) and Xenocide (1991). See for training of a boy to become the perfect commander against the "Bugger" enemy, insectoid enemies attacking our the solar system (cf. R. A. Heinlein's Starship Troopers). The training involves VR, in a simulation that proves only too real, and deadly — apparently (if — spoiler for later books — not quite) a total xenocide: the extermination of an alien species.
