They should perplex me. I should wonder what courage — which is the virtue they most value — has to do with a metal ring through your nostril. Instead my eyes cling to them wherever they go.

The train whistle blares, the sound resonating in my chest. The light fixed to the front of the train clicks on and off as the train hurtles past the school, squealing on iron rails. And as the last few cars pass, a mass exodus of young men and women in dark clothing hurl themselves from the moving cars, some dropping and rolling, others stumbling a few steps before regaining their balance. One of the boys wraps his arm around a girl’s shoulders, laughing.

Watching them is a foolish practice. I turn away from the window and press through the crowd to the Faction History classroom.

CHAPTER TWO

THE TESTS BEGIN after lunch. We sit at the long tables in the cafeteria, and the test administrators call ten names at a time, one for each testing room. I sit next to Caleb and across from our neighbor Susan.

Susan’s father travels throughout the city for his job, so he has a car and drives her to and from school every day. He offered to drive us, too, but as Caleb says, we prefer to leave later and would not want to inconvenience him.

Of course not.

The test administrators are mostly Abnegation volunteers, although there is an Erudite in one of the testing rooms and a Dauntless in another to test those of us from Abnegation, because the rules state that we can’t be tested by someone from our own faction. The rules also say that we can’t prepare for the test in any way, so I don’t know what to expect.

My gaze drifts from Susan to the Dauntless tables across the room. They are laughing and shouting and playing cards. At another set of tables, the Erudite chatter over books and newspapers, in constant pursuit of knowledge.

A group of Amity girls in yellow and red sit in a circle on the cafeteria floor, playing some kind of hand-slapping game involving a rhyming song. Every few minutes I hear a chorus of laughter from them as someone is eliminated and has to sit in the center of the circle. At the table next to them, Candor boys make wide gestures with their hands. They appear to be arguing about something, but it must not be serious, because some of them are still smiling.

At the Abnegation table, we sit quietly and wait. Faction customs dictate even idle behavior and supersede individual preference. I doubt all the Erudite want to study all the time, or that every Candor enjoys a lively debate, but they can’t defy the norms of their factions any more than I can.

Caleb’s name is called in the next group. He moves confidently toward the exit. I don’t need to wish him luck or assure him that he shouldn’t be nervous. He knows where he belongs, and as far as I know, he always has. My earliest memory of him is from when we were four years old. He scolded me for not giving my jump rope to a little girl on the playground who didn’t have anything to play with. He doesn’t lecture me often anymore, but I have his look of disapproval memorized.

I have tried to explain to him that my instincts are not the same as his — it didn’t even enter my mind to give my seat to the Candor man on the bus — but he doesn’t understand. “Just do what you’re supposed to,” he always says. It is that easy for him. It should be that easy for me.

My stomach wrenches. I close my eyes and keep them closed until ten minutes later, when Caleb sits down again.

He is plaster-pale. He pushes his palms along his legs like I do when I wipe off sweat, and when he brings them back, his fingers shake. I open my mouth to ask him something, but the words don’t come. I am not allowed to ask him about his results, and he is not allowed to tell me.

An Abnegation volunteer speaks the next round of names. Two from Dauntless, two from Erudite, two from Amity, two from Candor, and then: “From Abnegation: Susan Black and Beatrice Prior.”

I get up because I’m supposed to, but if it were up to me, I would stay in my seat for the rest of time. I feel like there is a bubble in my chest that expands more by the second, threatening to break me apart from the inside. I follow Susan to the exit. The people I pass probably can’t tell us apart. We wear the same clothes and we wear our blond hair the same way. The only difference is that Susan might not feel like she’s going to throw up, and from what I can tell, her hands aren’t shaking so hard she has to clutch the hem of her shirt to steady them.

Waiting for us outside the cafeteria is a row of ten rooms. They are used only for the aptitude tests, so I have never been in one before. Unlike the other rooms in the school, they are separated, not by glass, but by mirrors. I watch myself, pale and terrified, walking toward one of the doors. Susan grins nervously at me as she walks into room 5, and I walk into room 6, where a Dauntless woman waits for me.

She is not as severe-looking as the young Dauntless I have seen. She has small, dark, angular eyes and wears a black blazer — like a man’s suit — and jeans. It is only when she turns to close the door that I see a tattoo on the back of her neck, a black-and-white hawk with a red eye. If I didn’t feel like my heart had migrated to my throat, I would ask her what it signifies. It must signify something.

Mirrors cover the inner walls of the room. I can see my reflection from all angles: the gray fabric obscuring the shape of my back, my long neck, my knobby-knuckled hands, red with a blood blush. The ceiling glows white with light. In the center of the room is a reclined chair, like a dentist’s, with a machine next to it. It looks like a place where terrible things happen.

“Don’t worry,” the woman says, “it doesn’t hurt.”

Her hair is black and straight, but in the light I see that it is streaked with gray.

“Have a seat and get comfortable,” she says. “My name is Tori.”

Clumsily I sit in the chair and recline, putting my head on the headrest. The lights hurt my eyes. Tori busies herself with the machine on my right. I try to focus on her and not on the wires in her hands.

“Why the hawk?” I blurt out as she attaches an electrode to my forehead.

“Never met a curious Abnegation before,” she says, raising her eyebrows at me.

I shiver, and goose bumps appear on my arms. My curiosity is a mistake, a betrayal of Abnegation values.

Humming a little, she presses another electrode to my forehead and explains, “In some parts of the ancient world, the hawk symbolized the sun. Back when I got this, I figured if I always had the sun on me, I wouldn’t be afraid of the dark.”

I try to stop myself from asking another question, but I can’t help it. “You’re afraid of the dark?”

“I wasafraid of the dark,” she corrects me. She presses the next electrode to her own forehead, and attaches a wire to it. She shrugs. “Now it reminds me of the fear I’ve overcome.”

She stands behind me. I squeeze the armrests so tightly the redness pulls away from my knuckles. She tugs wires toward her, attaching them to me, to her, to the machine behind her. Then she passes me a vial of clear liquid.

“Drink this,” she says.

“What is it?” My throat feels swollen. I swallow hard. “What’s going to happen?”

“Can’t tell you that. Just trust me.”

I press air from my lungs and tip the contents of the vial into my mouth. My eyes close.

When they open, an instant has passed, but I am somewhere else. I stand in the school cafeteria again, but all the long tables are empty, and I see through the glass walls that it’s snowing. On the table in front of me are two baskets. In one is a hunk of cheese, and in the other, a knife the length of my forearm.

Behind me, a woman’s voice says, “Choose.”
