Ender’s Shadow by Orson Scott Card
This parallel novel retells the events of Ender’s Game from the perspective of another character. Ender’s Game was a gripping thrillride, and Ender’s Shadow is too. But since it’s the same thrillride, it’s just not quite as good the second time around.
The human race is at War with the “Buggers,” an insect-like alien race. The first battles went badly, and now as Earth prepares to defend itself against the imminent threat of total destruction at the hands of an inscrutable alien enemy, all focus is on the development and training of military geniuses who can fight such a war, and win.
The long distances of interstellar space have given hope to the defenders of Earth – they have time to train these future commanders up from childhood, forging them into an irresistible force in the orbital facility called the Battle School.
Andrew “Ender” Wiggin was not the only child in the Battle School; he was just the best of the best. In this new book, Card tells the story of another of those precocious generals, the one they called Bean – the one who became Ender’s right hand, his strategist, and his friend. One who was with him, part of his team, in the final battle against the Buggers.
