Shadow series (Orson Scott Card)

Follows the life of Ender Wiggin's comrade Bean, from his escape from the mean streets of Rotterdam, to his student days at the Battle School, and to his role as Ender's right hand ally, strategist, and friend in the epic struggle to save Earth from alien invaders.

A new chapter in the saga of Ender's Earth. Earth and its society have been changed irrevocably in the aftermath of Ender Wiggin's victory over the Formics. The unity forced upon the warring nations by an alien enemy has shattered. Nations are rising again, seeking territory and influence, and seeking to control the skills and loyalty of the children from the Battle School. But one person has a better idea. Peter Wiggin, Ender's older, more ruthless...

Bean moves with three of his children into a derelict space colony ship where they hope for a cure to engineered genes that give them high intelligence and short lives, a situation that is complicated when space-time distortions cause them to be forgotten by humanity.
