Ender's Game (1985) is a science fiction novel by American author Orson Scott Card. The book originated as the novelette "Ender's Game," published in the August 1977 issue of Analog Science Fiction and Fact. Elaborating on characters and plot lines depicted in the novel, Card later wrote additional books to form the Ender's Game series. Card released an updated version of Ender's Game in 1991, changing some political facts to accurately reflect the times. Set in Earth's future, the novel presents an imperiled humankind who have barely survived two conflicts with the Formics (an insectoid alien race also known as the "Buggers"). In preparation for an anticipated third invasion, an international fleet maintains a school to find and train future fleet commanders. The world's most talented children, including the novel's protagonist Ender Wiggin, are taken at a very young age to a training center known as the Battle School. There, teachers train them in the arts of war through increasingly difficult games including ones undertaken in zero gravity in the Battle Room where Ender's tactical genius is revealed.
