Ender's Game (Ender Wiggins Saga)

retain his old up-and-down orientation, his body attempting to right itself, searching for the gravity that wasn't there. Then he forced himself to change his view. He was hurtling toward a wall. That was down. And at once he had control of himself. He wasn't flying, he was falling. This was a dive. He could choose how he would hit the surface.
      I'm going too fast to catch ahold and stay, but I can soften the impact, can fly off at an angle if I roll when I hit and use my feet--
      It didn't work at all the way he had planned. He went off at an angle, but it was not the one he had predicted. Nor did he have time to consider. He hit another wall, this time too soon to have prepared for it. But quite accidentally he discovered a way to use his feet to control the rebound angle. Now he was soaring across the room again, toward the other boys who still clung to the wall. This time he had slowed enough to be able to grip a rung. He was at a crazy angle in relation to the other boys, but once again his orientation had changed, and as far as he could tell, they were all lying on the floor, not hanging on a wall, and he was no more upside down than they were.
      "What are you trying to do, kill yourself?" asked Shen.
      "Try it," Ender said. "The suit keeps you from hurting yourself, and you can control your bouncing with your legs, like this." He approximated the movement he had made.
      Shen shook his head-- he wasn't trying any fool stunt like that. But one boy did take off, not as fast as Ender had, because he didn't begin with a flip, but fast enough. Ender didn't even have to see his face to know that it was Bernard. And right after him, Bernard's best friend, Alai.
      Ender watched them cross the huge room, Bernard struggling to orient himself to the direction he thought of as the floor, Alai surrendering to the movement and preparing to rebound from the wall. No wonder Bernard broke his arm in the shuttle, Ender thought. He tightens up when he's flying. He panics. Ender stored the information away for future reference.
      And another bit of information, too. Alai did not push off in the same direction as Bernard. He aimed for a corner of the room. Their paths diverged more and more as they flew, and where Bernard made a clumsy, crunching landing and bounce on his wall, Alai did a glancing triple bounce on three surfaces near the corner that left him most of his speed and sent him flying off at a surprising angle. Alai shouted and whooped, and so did the boys watching him. Some of them forgot they were weightless and let go of the wall to clap their hands. Now they drifted lazily in many directions, waving their arms, trying to swim.
      Now, that's a problem, thought Ender. What if you catch yourself drifting? There's no way to push off.
      He was tempted to set himself adrift and try to solve the problem by trial and error. But he could see the others, their useless efforts at control, and he couldn't think of what he would do that they weren't already doing.
      Holding onto the floor with one hand, he fiddled idly with the toy gun that was attached to his suit in front, just below the shoulder. Then he remembered the hand rockets sometimes used by marines when they did a boarding assault on an enemy station. He pulled the gun from his suit and examined it. He had pushed all the buttons back in the room, but the gun did nothing there. Maybe here in the battleroom it would work. There were no instructions on it. No labels on the controls. The trigger was obvious-- he had had toy guns, as all children had, almost since infancy. There were two buttons that his thumb could easily reach, and several others along the bottom of the shaft that were almost inaccessible without using two hands. Obviously, the two buttons near his thumb were meant to be instantly usable.
      He aimed the gun at the floor and pulled back on the trigger. He felt the gun grow instantly warm; when he let go of the trigger, it cooled at once. Also, a tiny circle of light appeared on the floor where he was aiming.
      He thumbed the red button at the top of the gun, and pulled the trigger again. Same thing.
      Then he pushed the white button. It gave a bright flash of light that illuminated a wide area, but not as intensely. The gun was quite cold when the button was pressed.
      The red button makes it like a laser-- but it is not a laser, Dap had said-- while the white button makes it a lamp. Neither will be much help when it comes to
