Ender's Game (novel series)
The Shadow series (also called the "Bean Quartet") starts with Ender's Shadow, followed by 4 other books about the lives of the people Ender left behind. Ender's Shadow occurs at the same time and place (Battle School) as Ender's Game does, but instead in the view of Bean rather than Ender. Shadow of the Hegemon, Shadow Puppets, and Shadow of the Giant are stories about world dominance on Earth after the Bugger War in which the children at Battle School and Ender's older brother, Peter Wiggin, are main characters. Shadows in Flight, a sequel to Shadow of the Giant, is planned to come out; however, it will start after Children of the Mind, not Shadow of the Giant, and will combine the two Ender's Game series: the Ender series and the Shadow series. Shadows in Flight has recently been renamed to Shadows Alive.
