Ender's Game / Ender's Shadow

This omnibus pairs Ender's Game with its parallel novel Ender's Shadow: the first follows Andrew Ender Wiggin, a gifted child pushed through Battle School's brutal war games to prepare him to command Earth's defense against an insectoid alien threat, and the second retells those same events through Bean, a tiny, brilliant street orphan who watches Ender's rise from the shadows while hiding a secret about his own origin.
