Ender's Game hexalogy

The Ender's Game series (often referred to as the Ender saga and also the Enderverse) is a series of science fiction books written by American author Orson Scott Card. The series started with the novelette Ender's Game, which was later expanded into the novel of the same title. It currently consists of sixteen novels and thirteen short stories. The first two novels in the series, Ender's Game and Speaker for the Dead, each won both the Hugo and Nebula Awards. The series is set in a future where mankind is facing annihilation by an aggressive alien society, an insect-like race known formally as "Formics", but more colloquially as "Buggers". The series protagonist, Andrew "Ender" Wiggin, is one of the child soldiers trained at Battle School (and eventually Command School) to be the future leaders for the protection of Earth.
