I STUDIED TRIGONOMETRY FOR a month. I sometimes dreamed about sine, cosine and tangent, about mysterious angles and concussed computations, but for all this I made no real progress. I could not self-teach trigonometry. But I knew someone who had.

Tyler told me to meet him at our aunt Debbie’s house, because she lived near Brigham Young University. The drive was three hours. I felt uncomfortable knocking on my aunt’s door. She was Mother’s sister, and Tyler had lived with her during his first year at BYU, but that was all I knew of her.

Tyler answered the door. We settled in the living room while Debbie prepared a casserole. Tyler solved the equations easily, writing out orderly explanations for every step. He was studying mechanical engineering, set to graduate near the top of his class, and soon after would start a PhD at Purdue. My trig equations were far beneath his abilities, but if he was bored he didn’t show it; he just explained the principles patiently, over and over. The gate opened a little, and I peeked through it.

Tyler had gone, and Debbie was pushing a plate of casserole into my hands, when the phone rang. It was Mother.

“There’s been an accident in Malad,” she said.

MOTHER HAD LITTLE INFORMATION. Shawn had fallen. He’d landed on his head. Someone had called 911, and he’d been airlifted to a hospital in Pocatello. The doctors weren’t sure if he would live. That was all she knew.

I wanted more, some statement of the odds, even if it was just so I could reason against them. I wanted her to say, “They think he’ll be fine” or even “They expect we’ll lose him.” Anything but what she was saying, which was, “They don’t know.”

Mother said I should come to the hospital. I imagined Shawn on a white gurney, the life leaking out of him. I felt such a wave of loss that my knees nearly buckled, but in the next moment I felt something else. Relief.

There was a storm coming, set to lay three feet of snow over Sardine Canyon, which guarded the entrance to our valley. Mother’s car, which I had driven to Debbie’s, had bald tires. I told Mother I couldn’t get through.

THE STORY OF HOW Shawn fell would come to me in bits and pieces, thin lines of narrative from Luke and Benjamin, who were there. It was a frigid afternoon and the wind was fierce, whipping the fine dust up in soft clouds. Shawn was standing on a wooden pallet, twenty feet in the air. Twelve feet below him was a half-finished concrete wall, with rebar jutting outward like blunt skewers. I don’t know for certain what Shawn was doing on the pallet, but he was probably fitting posts or welding, because that was the kind of work he did. Dad was driving the forklift.

I’ve heard conflicting accounts of why Shawn fell.^* Someone said Dad moved the boom unexpectedly and Shawn pitched over the edge. But the general consensus is that Shawn was standing near the brink, and for no reason at all stepped backward and lost his footing. He plunged twelve feet, his body revolving slowly in the air, so that when he struck the concrete wall with its outcropping of rebar, he hit headfirst, then tumbled the last eight feet to the dirt.

This is how the fall was described to me, but my mind sketches it differently—on a white page with evenly spaced lines. He ascends, falls at a slope, strikes the rebar and returns to the ground. I perceive a triangle. The event makes sense when I think of it in these terms. Then the logic of the page yields to my father.

Dad looked Shawn over. Shawn was disoriented. One of his pupils was dilated and the other wasn’t, but no one knew what that meant. No one knew it meant there was a bleed inside his brain.

Dad told Shawn to take a break. Luke and Benjamin helped him prop himself against the pickup, then went back to work.

The facts after this point are even more hazy.

The story I heard was that fifteen minutes later Shawn wandered onto the site. Dad thought he was ready to work and told him to climb onto the pallet, and Shawn, who never liked being told what to do, started screaming at Dad about everything—the equipment, the granary designs, his pay. He screamed himself hoarse, then just when Dad thought he had calmed down, he gripped Dad around the waist and flung him like a sack of grain. Before Dad could scramble to his feet Shawn took off, leaping and howling and laughing, and Luke and Benjamin, now sure something was very wrong, chased after him. Luke reached him first but couldn’t hold him; then Benjamin added his weight and Shawn slowed a little. But it wasn’t until all three men tackled him—throwing his body to the ground, where, because he was resisting, his head hit hard—that he finally lay still.

No one has ever described to me what happened when Shawn’s head struck that second time. Whether he had a seizure, or vomited, or lost consciousness, I’m not sure. But it was so chilling that someone—maybe Dad, probably Benjamin—dialed 911, which no member of my family had ever done before.

They were told a helicopter would arrive in minutes. Later the doctors would speculate that when Dad, Luke and Benjamin had wrestled Shawn to the ground—and he’d sustained a concussion—he was already in critical condition. They said it was a miracle he hadn’t died the moment his head hit the ground.

I struggle to imagine the scene while they waited for the chopper. Dad said that when the paramedics arrived, Shawn was sobbing, begging for Mother. By the time he reached the hospital, his state of mind had shifted. He stood naked on the gurney, eyes bulging, bloodshot, screaming that he would rip out the eyes of the next bastard who came near him. Then he collapsed into sobs and finally lost consciousness.

SHAWN LIVED THROUGH THE NIGHT.

In the morning I drove to Buck’s Peak. I couldn’t explain why I wasn’t rushing to my brother’s bedside. I told Mother I had to work.

“He’s asking for you,” she said.

“You said he doesn’t recognize anyone.”

“He doesn’t,” she said. “But the nurse just asked me if he knows someone named Tara. He said your name over and over this morning, when he was asleep and when he was awake. I told them Tara is his sister, and now they’re saying it would be good if you came. He might recognize you, and that would be something. Yours is the only name he’s said since he got to the hospital.”

I was silent.

“I’ll pay for the gas,” Mother said. She thought I wouldn’t come because of the thirty dollars it would cost in fuel. I was embarrassed that she thought that, but then, if it wasn’t the money, I had no reason at all.

“I’m leaving now,” I said.

I remember strangely little of the hospital, or of how my brother looked. I vaguely recall that his head was wrapped in gauze, and that when I asked why, Mother said the doctors had performed a surgery, cutting into his skull to relieve some pressure, or stop a bleed, or repair something—actually, I can’t remember what she said. Shawn was tossing and turning like a child with a fever. I sat with him for an hour. A few times his eyes opened, but if he was conscious, he didn’t recognize me.

When I came the next day, he was awake. I walked into the room and he blinked and looked at Mother, as if to check that she was seeing me, too.

“You came,” he said. “I didn’t think you would.” He took my hand and then fell asleep.

I stared at his face, at the bandages wrapped around his forehead and over his ears, and was bled of my bitterness. Then I understood why I hadn’t come sooner. I’d been afraid of how I would feel, afraid that if he died, I might be glad.

I’m sure the doctors wanted to keep him in the hospital, but we didn’t have insurance, and the bill was already so large that Shawn would be making payments a decade later. The moment he was stable enough to travel, we took him home.

He lived on the sofa in the front room for two months. He was physically weak—it was all he had in him to make it to the bathroom and back. He’d lost his hearing completely in one ear and had trouble hearing with the other, so he often turned his head when people spoke to him, orienting his better ear toward them, rather than his eyes. Except for this strange movement and the bandages from the surgery, he looked normal, no swelling, no bruises. According to the doctors, this was because the damage was very serious: a lack of external injuries meant the damage was all internal.

It took some time for me to realize that although Shawn looked the same, he wasn’t. He seemed lucid, but if you listened carefully his stories didn’t make sense. They weren’t really stories at all, just one tangent after another.

I felt guilty that I hadn’t visited him immediately in the hospital, so to make it up to him I quit my job and tended him day and night. When he wanted water, I fetched it; if he was hungry, I cooked.

Sadie started coming around, and Shawn welcomed her. I looked forward to her visits because they gave me time to study. Mother thought it was important that I stay with Shawn, so no one interrupted me. For the first time in my life I had long stretches in which to learn—without having to scrap, or strain tinctures, or check inventory for Randy. I examined Tyler’s notes, read and reread his careful explanations. After a few weeks of this, by magic or miracle, the concepts took hold. I retook the practice test. The advanced algebra was still indecipherable—it came from a world beyond my ability to perceive—but the trigonometry had become intelligible, messages written in a language I could understand, from a world of logic and order that only existed in black ink and on white paper.

The real world, meanwhile, plunged into chaos. The doctors told Mother that Shawn’s injury might have altered his personality—that in the hospital, he had shown tendencies toward volatility, even violence, and that such changes might be permanent.

He did succumb to rages, moments of blind anger when all he wanted was to hurt someone. He had an intuition for nastiness, for saying the single most devastating thing, that left Mother in tears more nights than not. These rages changed, and worsened, as his physical strength improved, and I found myself cleaning the toilet every morning, knowing my head might be inside it before lunch. Mother said I was the only one who could calm him, and I persuaded myself that that was true. Who better? I thought. He doesn’t affect me.

Reflecting on it now, I’m not sure the injury changed him that much, but I convinced myself that it had, and that any cruelty on his part was entirely new. I can read my journals from this period and trace the evolution—of a young girl rewriting her history. In the reality she constructed for herself nothing had been wrong before her brother fell off that pallet. I wish I had my best friend back, she wrote. Before his injury, I never got hurt at all.

* My account of Shawn’s fall is based on the story as it was told to me at the time. Tyler was told the same story; in fact, many of the details in this account come from his memory. Asked fifteen years later, others remember it differently. Mother says Shawn was not standing on a pallet, only on forklift tines. Luke remembers the pallet, but substitutes a metal drain, with the grating removed, in place of the rebar. He says the fall was twelve feet, and that Shawn began acting strangely as soon as he regained consciousness. Luke has no memory of who dialed 911, but says there were men working in a nearby mill, and he suspects that one of them called immediately after Shawn fell.

There was a moment that winter. I was kneeling on the carpet, listening to Dad testify of Mother’s calling as a healer, when my breath caught in my chest and I felt taken out of myself. I no longer saw my parents or our living room. What I saw was a woman grown, with her own mind, her own prayers, who no longer sat, childlike, at her father’s feet.

I saw the woman’s swollen belly and it was my belly. Next to her sat her mother, the midwife. She took her mother’s hand and said she wanted the baby delivered in a hospital, by a doctor. I’ll drive you, her mother said. The women moved toward the door, but the door was blocked—by loyalty, by obedience. By her father. He stood, immovable. But the woman was his daughter, and she had drawn to herself all his conviction, all his weightiness. She set him aside and moved through the door.

I tried to imagine what future such a woman might claim for herself. I tried to conjure other scenes in which she and her father were of two minds. When she ignored his counsel and kept her own. But my father had taught me that there are not two reasonable opinions to be had on any subject: there is Truth and there are Lies. I knelt on the carpet, listening to my father but studying this stranger, and felt suspended between them, drawn to each, repelled by both. I understood that no future could hold them; no destiny could tolerate him and her. I would remain a child, in perpetuity, always, or I would lose him.

I WAS LYING ON MY BED, watching the shadows my feeble lamp cast on the ceiling, when I heard my father’s voice at the door. Instinctively I jerked to my feet in a kind of salute, but once I was standing I wasn’t sure what to do. There was no precedent for this: my father had never visited my room before.

He strode past me and sat on my bed, then patted the mattress next to him. I took my seat, nervously, my feet barely touching the floor. I waited for him to speak, but the moments passed silently. His eyes were closed, his jaw slackened, as if he were listening to seraphic voices. “I’ve been praying,” he said. His voice was soft, a loving voice. “I’ve been praying about your decision to go to college.”
