The first four books of the Ender's Shadow series in one boxed set: Ender's Shadow, Shadow of the Hegemon, Shadow Puppets, and Shadow of the Giant, from bestselling author Orson Scott Card.
Ender's Shadow Welcome to Battle School. Growing up is never easy. But try living on the mean streets as a child begging for food and fighting like a dog with ruthless gangs of starving kids who wouldn't hesitate to pound your skull into pulp for a scrap of apple. If Bean has learned anything on the streets, it's how to survive. And not with fists. He is way too small for that. But with brains. Shadow of the Hegemon The War is over, won by Ender Wiggin and his team of brilliant child-warriors. The enemy is destroyed, the human race is saved. Ender himself refuses to return to the planet, but his crew has gone home to their families, scattered across the globe. The Battle School is no more. Shadow Puppets Earth and its society has been changed irrevocably in the aftermath of Ender Wiggin's victory over the Formics--the unity enforced upon the warring nations by an alien enemy has shattered. Nations are rising again, seeking territory and influence, and most of all, seeking to control the skills and loyalty of the children from the Battle School. Shadow of the Giant Bean, once the smallest student at the Battle School, and Ender Wiggin's right hand, has grown to be a power on Earth. He served the Hegemon as strategist and general in the terrible wars that followed Ender's defeat of the alien empire attacking Earth. Now he wishes for a safe place to build a family--something he has never known--but there is nowhere on Earth that does not harbor his enemies.
