Essef - When humanity is under threat from an alien race; Ender Wiggin; at the age of six; leaves his family on Earth to journey to the Belt. There he enters Battle School; where his life is strictly disciplined by mind games and computer mock-battles fought in deadly earnest. Instinct; compassion and genius make Ender unequalled. But while he trains; the invasion approaches fast. And Ender will be pushed to the limits of endurance; for he is a unique destiny... Without a doubt this is one of the best Essef novels ever written.
