Dave recommended this book as a classic.
Luckily for me it was released in audio format for the 20th Anniversary edition.
Ender Wiggin is a very bright young boy with a powerful skill. One of a group of children bred to be military geniuses and save Earth from an inevitable attack by aliens, known here as “buggers,” Ender becomes unbeatable in war games and seems poised to lead Earth to triumph over the buggers. Meanwhile, his brother and sister plot to wrest power from Ender. Twists, surprises and interesting characters elevate this novel into status as a bona fide page turner. It captured the Nebula and Hugo Awards.
It is superb. Very original. Something like Lord of the Flies meets Starship Troopers.
The ending of Ender’s Game came as a complete shock.
