Psi Special Forces—that’s what the driver of the bus had called himself and the others when they collected us from the warehouse. You are to come with us on authority of the Psi Special Forces commander, Joseph Traylor. He held up a paper to prove it, so I guess it was true. I had been taught not to argue with adults, anyway.

The bus took a deep dip as it pulled off the narrow road and onto a smaller dirt one. The new vibrations woke whoever had been lucky or exhausted enough to fall asleep. They also sent the black uniforms into action. The men and women stood straighter, and their attention snapped toward the windshield.

I saw the towering fence first. The darkening gray sky cast everything in a moody, deep blue, but not the fence. It was glowing silver as the wind whistled through its open pockets. Just below my window were dozens of men and women in full uniform, escorting the bus in at a brisk jog. The PSFs in the control booth at the gate stood and saluted the driver as he navigated past them.

The bus lurched to a stop, and we were all forced to stay deathly still as the camp gate slid shut behind us. The locks cracked through the silence like thunder as they came together again. We were not the first bus through—that had come a year before. We were not the last bus, either. That would come in three more years, when the camp’s occupancy maxed out.

There was a single breath of stillness before a soldier in a black rain poncho rapped on the bus door. The driver reached over and pulled the lever—and ended anyone’s hope that this was a short pit stop.

The PSF was an enormous man, the kind you’d expect to play an evil giant in a movie, or a villain in a cartoon. He kept his hood up, masking his face, hair, and anything that would have let me recognize him later. I guess it didn’t matter. He wasn’t speaking for himself. He was speaking for the camp.

“You will stand and exit the bus in an orderly fashion,” he yelled. The driver tried to hand him the microphone, but the soldier knocked it away with his hand. “You will be divided into groups of ten, and you will be brought in for testing. Do not try to run. Do not speak. Do not do anything other than what is asked of you. Failure to follow these instructions will be met with punishment.”

At ten, I was one of the younger kids on the bus, though there were certainly a few kids younger. Most seemed to be twelve, even thirteen. The hate and mistrust burning in the soldiers’ eyes might have shrunken my spine, but it only sparked rebellion in the older kids.

“Go screw yourself!” someone yelled from the back of the bus.

We all turned at once, just in time to see the PSF with the flaming red hair launch the butt of her rifle into the teenage boy’s mouth. He let out a shriek of pain and surprise as the soldier did it again, and I saw a faint spray of blood burst from his mouth when he took his next, angry breath. With his hands behind his back, there was no way he could block the attack. He just had to take it.

They began moving kids off the bus, one seat of four at a time. But I was still watching that kid, the way he seemed to cloud the air around him with silent, toxic fury. I don’t know if he felt me staring, or what, but the boy turned around and met my gaze. He nodded at me, like an encouragement. And when he smiled, it was around a mouthful of bloody teeth.

I felt myself being hauled up and out of my seat, and almost before I realized what was happening, I was slipping down the wet bus steps and tumbling into the pouring rain. A different PSF lifted me off my knees and guided me in the direction of two other girls about my age. Their clothes clung to them like old skin, translucent and drooping.

There were nearly twenty PSFs on the ground, swarming the neat small lines of kids. My feet had been completely swallowed by the mud, and I was shivering in my pajamas, but no one took notice, and no one came up to cut the plastic binding our hands. We waited, silently, tongues clamped between our teeth. I looked up to the clouds, turning my face to the pounding rain. It looked like the sky was falling, piece by piece.

The last groups of four were being lifted off the bus and dropped onto the ground, including the boy with the broken face. He was the last one off, just behind a tall blond girl with a blank stare. I could barely make them out through the sheet of rain and the foggy bus windows, but I was sure I saw the boy lean forward and whisper something into the girl’s ear, just as she took the first step off the bus.

She nodded, a quick jerk of her chin. The second her shoes touched the mud, she bolted to the right, ducking around the nearest PSF’s hands. One of the PSFs barked out a terrifying “Stop!” but she kept running, straight for the gates. With everyone’s attention turned toward her, no one thought to look back at the boy still on the bus—no one but me. He came slinking down the steps, the front of his white hooded sweatshirt stained with his own blood. The same PSF who had hit him before was now helping him down to the ground, as she had done for the rest of us. I watched her fingers close around his elbow and felt the echo of her grip on my own newly bruised skin; I watched him turn and say something to her, his face a mask of perfect calm.

I watched the PSF let go of his arm, take her gun out of its holster, and, without a word—without even blinking—stick the barrel inside of her mouth and pull the trigger.

I don’t know if I screamed aloud, or if the strangled sound had come from the woman waking up to what she was doing, two seconds too late to stop it. The image of her face—her slack jaw, her eyes bulging out of her skull, the ripple of suddenly loose skin—stayed burned into the air like a photonegative far longer than the explosion of pink, misty blood and clumps of hair against the bus.

The kid standing next to me dropped into a dead faint, and then there wasn’t a single one of us that wasn’t screaming.

The PSF hit the ground the exact same moment the girl was tackled into the mud. The rain washed the soldier’s blood down off the bus windows and yellow panels, stretching the bloated dark lines, drawing them out as they disappeared completely. It was that fast.

The boy was looking only at us. “Run!” he yelled through his broken teeth. “What are you doing? Run—run!”

And the first thing that went through my mind wasn’t What are you? or even Why?

It was But I have nowhere else to go.

He might as well have blown the entire bus up for the panic it caused. Some kids listened and tried to bolt for the fence, only to have their path blocked by the line of soldiers in black that seemed to pour out of the air. Most just stood there and screamed, and screamed, and screamed, the rain falling all around, the mud sucking their feet down firmly in place. A girl knocked me down to the ground with her shoulder as the other PSFs rushed for the boy, still standing in the bus doorway. The soldiers were yelling at us to sit on the ground, to stay frozen there. I did exactly as I was told.
