A century before the events of Ender's Game, an alien spaceship enters the solar system and soon makes known its hostile intentions by destroying harmless human ships. Then, it wipes out a ragtag fleet of asteroid miners who have banded together in a desperate attempt to stop it. All of the adult male members of Victor Delgado's extended clan die in the battle. The survivors are unable to transmit a warning, so Victor volunteers for a near-suicidal mission to try to reach Earth in a tiny, hastily converted unmanned cargo ship. He makes it to the Moon, but is unable to get the authorities to take him seriously. Thus, humanity is totally unprepared when the First Formic War starts. The invader sends three enormous landing craft to southeast China. The Formics emerge and use gas to defoliate the area and kill everyone. Despite suffering stupendous losses, the suspicious Chinese government refuses outside help. Before the landing, Mazer Rackham had been training the Chinese military on a new transport aircraft, the HERC, in exchange for training on their new invention, drill sledges that can tunnel quickly underground. During the Formic invasion, he saves Bingwen, a very intelligent eight-year-old Chinese boy, but is then shot down. Bingwen saves his life, with the remote help of Mazer's romantic interest, Kim. Bingwen and Mazer then set off to destroy the nearest Formic lander. The Mobile Operations Police, a small but elite international force, enters China. The MOPs save Bingwen and Mazer from a Formic attack. The lander is heavily shielded, but it does not extend underground. Mazer manages to find some drill sledges and HERCs to transport them close to the lander. MOP Captain Wit O'Toole obtains a tactical nuclear weapon from anonymous Chinese who do not agree with their government's stance on foreign assistance. They destroy the lander, but then Captain Shenzu arrives and places Mazer under arrest. Meanwhile, Victor and Imala manage to drift close to the Formic ship, using a disguised ship provided by Lem Jukes to avoid being destroyed. Victor breaks into the alien ship through a gun port.
