A generation later came the second invasion, and this time they won only because of one man: Mazer Rackham. If they come again, humanity's defense would need many Rackhams. The Battle School exists to find these new saviors of mankind. Every 6 months, twenty of the Earth's most brilliant six-year-olds launch into space, bound for this school positioned in an undisclosed location. ---
