Ender's Game stands out to me due to its appeal to many different ages of potential readers. Orson Scott Card manages to capture the voices and mindsets of children and teenagers perfectly. His characters are easy to relate to, and the troubles of Ender become the concerns of the reader very quickly. Explosive action and taut suspense culminate in a groundbreaking plot twist as Ender, Card's hero and pivot point, fights for the survival of Earth and humanity.
A veteran of years of simulated war games, Ender believes he is engaged in one more computer war game when in truth he is commanding the last fleet of Earth against an alien race seeking the complete destruction of Earth.
