Ender's Game (Ender Wiggins Saga)

easier than most of their recent exercises.
      Mazer shrugged when Ender told him so. "This is a simulation of a real invasion. There had to be one battle in which they didn't know what we could do. Now your work begins. Try not to be too arrogant about the victory. I'll give you the real challenges soon enough.”
      Ender practiced ten hours a day with his squadron leaders, but not all at once; he gave them a few hours in the afternoon to rest. Simulated battles under Mazer's supervision came every two or three days, and as Mazer had promised, they were never so easy again. The enemy quickly abandoned its attempt to surround Ender, and never again grouped its forces closely enough to allow a chain reaction. There was something new every time, something harder. Sometimes Ender had only a single starship and eight fighters; once the enemy dodged through an asteroid belt; sometimes the enemy left stationary traps, large installations that blew up if Ender brought one of his squadrons too close, often crippling or destroying some of Ender's ships. "You cannot absorb losses!" Mazer shouted at him after one battle. "When you get into a real battle you won't have the luxury of an infinite supply of computer-generated fighters. You'll have what you brought with you and nothing more . Now get used to fighting without unnecessary waste.”
      "It wasn't unnecessary waste, Ender said. "I can't win battles if I'm so terrified of losing a ship that I never take any risks.”
      Mazer smiled. "Excellent, Ender. You're beginning to learn. But in a real battle, you would have superior officers and, worst of all, civilians shouting those things at you. Now, if the enemy had been at all bright, they would have caught you here , and taken Tom's squadron." Together they went over the battle; in the next practice, Ender would show his leaders what Mazer had shown him, and they'd learn to cope with it the next time they saw it.
      They thought they had been ready before, that they had worked smoothly together as a team. Now, though, having fought through real challenges together, they all began to trust each other more than ever, and battles became exhilarating. They told Ender that the ones who weren't actually playing would come into the simulator rooms and watch. Ender imagined what it would be like to have his friends there with him, cheering or laughing or gasping with apprehension; sometimes he thought it would be a great distraction, but other times he wished for it with all his heart. Even when he had spent his days lying out in the sunlight on a raft in a lake, he had not been so lonely. Mazer Rackham was his companion, was his teacher, but was not his friend.
      He said nothing, though. Mazer had told him there would be no pity, and his private unhappiness meant nothing to anyone. Most of the time it meant nothing even to Ender. He kept his mind on the game, trying to learn from the battles. And not just the particular lessons of that battle, but what the buggers might have done if they had been more clever, and how Ender would react if they did it in the future. He lived with past battles and future battles both, waking and sleeping, and he drove his squadron leaders with an intensity that occasionally provoked rebelliousness.
      "You're too kind to us," said Alai one day. "Why don't you get annoyed with us for not being brilliant every moment of every practice. If you keep coddling us like this we'll think you like us.”
      Some of the others laughed into their microphones. Ender recognized the irony, of course, and answered with a long silence. When he finally spoke, he ignored Alai's complaint. "Again," he said, "and this time without self-pity." They did it again, and did it right.
      But as their trust in Ender as a commander grew, their friendship, remembered from the Battle School days, gradually disappeared. It was to each other that they became close; it was with each other that they exchanged confidences. Ender was their teacher and commander, as distant from them as Mazer was from him, and as demanding.
      They fought all the better for it. And Ender was not distracted from his work.
      At least, not while he was awake. As he drifted off to sleep each night, it was with thoughts of the simulator playing through his mind. But in the night he thought of other things. Often he remembered the corpse of the Giant, decaying steadily; he did not remember it, though, in the pixels of the picture on his desk.
