What is the author's style in Ender's Game by Orson Scott Card?

The structure of Ender's Game is fairly straightforward, relating events in a fairly linear style. Although told in third person, most of these events are portrayed from Ender's perspective so that the reader does not know more than he does. An interesting complement to Ender's story is the conversations between Colonel Graff and his associates that preface each chapter. These conversations provide additional perspective, providing more information to the reader than can be found from Ender's limited point of view. The chapters on Valentine and Peter's efforts bring additional background to the eventual conclusion, involving the adult Ender's new career as a Speaker for the Dead.
