Ok, the original idea was buy the Ender`s Game book (by Orson Scott Card), but I dont find it :( so, I bring to home the Ender`s Shadow and Shadow of the Hegemon books (parallel novels to the Ender`s saga). I just finished the Ender´s Shadow a few hours and… wow! what a book! not a masterpiece but works. Heres a link to the original short story. By the way, check the kick ass covers by Leo Flores, unfortunately, I dont find links to any gallery of his work.
