Enders Game is the best book in the Ender's series, with each successive book being not quite as good as the previous.

Enders Game tells the story of Ender, the child selected to save the earth from alien invasion. I think I would have preferred it if he had written only Ender's Game and left the rest of the series in his imagination.

NOTE: I absolutely despised the book Lost Boys.
