It's a nazi novel, I know that much.

"Card made it very clear in interviews in the 1980's that he was doing God's work with his writing. In essence he was the anti-Iain Banks; instead of reclaiming SF for liberalism, he was reclaiming it for moral absolutism. And he was doing it by being sneaky. Kessel nicely explains some of this sneakiness even without admitting the Hitler Hypothesis. Ender Wiggin, it turns out, is more than anything else one of the nice young men with the suits and ties and bicycles who just knocked on your door and who would like to talk with you about important matters of salvation and eternity. Except that he's dressed in a pizza delivery uniform and not admitting his real purpose."
