Anyway, I turned on my computer and stared at the cover of my trigonometry textbook while I waited for the computer to boot up. I used to think that teachers who gave homework on weekends should be forced to grade papers for an eternity in hell. Now that I have a sense of what hell might be like, I don’t think grading papers forever would be that bad. As soon as Windows started, I pushed the trig book aside and loaded up World of Warcraft. I figured there’d be enough time to do my homework Sunday night.

None of my friends were online, so I flew my character to the Storm Peaks to work on daily quests and farm some gold. WoW used to hold my interest the way little else could. The daily quests were just challenging enough to keep my mind occupied, despite the fact that I’d done them dozens of times. Even gold farming, by far the most boring activity, brought the satisfaction of earning coin, making my character more powerful, achieving something. Every now and then I had to remind myself that it was all only ones and zeros in a computer in Los Angeles, or I might have gotten truly addicted. I wonder if anyone will ever play World of Warcraft again.

Three hours later and over 1,000 gold richer, I got the first hint that this would not be a normal Friday evening. There was a rumble, almost too low to hear, and the house shook a little. An earthquake, maybe, although we never have earthquakes in Iowa.

The power went out. I stood to open the curtains. I thought there might be enough light to read by, at least for a while.

Then it happened.

I heard a cracking noise, like the sound the hackberry tree in our backyard had made when Dad cut it down last year, but louder: a forest of hackberries, breaking together. The floor tilted, and I fell across the suddenly angled room, arms and legs flailing. I screamed but couldn’t hear myself over the noise: a boom and then a whistling sound—incoming artillery from a war movie, but played in reverse. My back hit the wall on the far side of the room, and the desk slid across the floor toward me. I wrapped myself into a ball, hands over the back of my neck, praying my desk wouldn’t crush me. It rolled, painfully clipped my right shoulder, and came to rest above me, forming a small triangular space between the floor and wall. I heard another crash, and everything shook violently for a second.

I’d seen those stupid movies where the hero gets tossed around like a rag doll and then springs up, unhurt and ready to fight off the bad guys. If I were the star in one of those, I suppose I would have jumped up, thrown the desk aside, and leapt to battle whatever malevolent god had struck my house. I hate to disappoint, but I just lay there, curled in a ball, shaking in pure terror. It was too dark under the desk to see anything beyond my quivering knees. Nor could I hear—the noise of those few violent seconds had left my ears ringing loudly enough to drown out a marching band if one had been passing by. Plaster dust choked the air, and I fought back a sneeze.

I lay in that triangular cave for a minute, maybe longer. My body mostly quit shaking, and the ringing in my ears began to fade. I poked my right shoulder gingerly; it felt swollen, and touching it hurt. I could move the arm a little, so I figured it wasn’t broken. I might have lain there longer checking my injuries, but I smelled something burning.

That whiff of smoke was enough to transform my sit-here-trembling terror into get-the-hell-out-of-here terror. There was enough room under the desk to unball myself, but I couldn’t stretch out. Ahead I felt a few hollow spaces amidst a pile of loose books. I’d landed wedged against my bookcase. I shoved it experimentally with my good arm—it wasn’t going anywhere.

The burning smell intensified. I slapped my left hand against the desk above me and pushed upward. I’d moved that heavy desk around by myself before, no problem. But now, when I really needed to move it, nothing . . . it wouldn’t shift even a fraction of an inch.

That left trying to escape in the direction my feet pointed. But I couldn’t straighten my legs—they bumped against something just past the edge of the desk. I planted my feet on the obstacle and pushed. It shifted a little. Encouraged, I stretched my good arm through the shelves, placing my hand against the back of the bookcase. And snatched it away in shock—the wall behind the bookcase was warm. Not hot enough to burn, but warm enough to give me an ugly mental picture of my fate if I couldn’t escape—and soon.

I hadn’t felt particularly claustrophobic at first. The violence of being thrown across the room left no time to feel anything but scared. Now, with the air heating up, terror rose from my gut. Trapped. Burned alive. Imagining my future got me hyperventilating. I inhaled a lungful of dust and choked, coughing.

Calm down, Alex, I told myself. I took two quick breaths in through my nose and puffed them out through my mouth—recovery breathing, like I’d use after a hard round of sparring in taekwondo. I could do this.

I slammed my hand back against the wall, locked my elbow, and shoved with my feet—hard. The obstacle shifted slightly. I bellowed and bore down on it, trying to snap my knees straight. There’s a reason martial artists yell when we break boards—it makes us stronger. Something gave then; I felt it shift and heard the loud thunk of wood striking wood. Debris fell on my ankles—maybe chunks of plaster and insulation from the ceiling. A little kicking freed my legs, stirring up more dry, itchy dust.

I forced my way backward into the new hole. There were twelve, maybe sixteen inches of space before I hit something solid again. The air was getting hotter. Sweat trickled sideways off my face. I couldn’t dislodge the blockage, so I bent at the waist, contorting my body around the desk into an L shape.

I kept shoving my body backward into the gap between a fallen ceiling joist and my desk, pushing myself upward along the tilted floor. A lurid orange light flickered down into the new space. When I’d wormed my way fully alongside the joist, I jammed my head and shoulders up through the broken ceiling into what used to be the unfinished attic above my room.

A wall of heat slammed into me, like opening the oven with my face too close. Long tendrils of flame licked into the attic above my sister’s collapsed bedroom, cat tongues washing the rafters and underside of the roof decking with fire. Smoke billowed up and pooled under the peak of the roof. The front part of the attic had collapsed, joists leaning downward at crazy angles. What little I could see of the back of the attic looked okay. An almost perfectly round hole had been punched in the roof above my sister’s bedroom. I glimpsed a coin of deep blue sky through the flames eating at the edges of the hole.

I dragged myself up the steeply angled joists, trying to reach the back of the attic. My palms were slippery with sweat, and my right shoulder screamed in pain. But I got it done, crawling upward with the heat at my back urging me on.

The rear of the attic looked normal—aside from the thick smoke and dust. I crawled across the joists, pushing through the loose insulation to reach the boxes of holiday decorations my mother had stored next to the pull-down staircase.

I struggled to open the staircase—it was meant to be pulled open with a cord from the hallway below. I crawled onto it to see if my weight would force it down. The springs resisted at first, but then the hatch picked up speed and popped open with a bang. It was all I could do to hold on and avoid tumbling into the hallway below. It bruised my knees pretty good, too. I flipped the folded segments of the stair open so I could step down to the second floor.

Keeping my head low to avoid the worst of the smoke, I scuttled down the hallway to the staircase. This part of the house seemed undamaged. When I reached the first floor, I heard banging and shouting from the backyard. I ran to the back door and glanced through the window. Our neighbor from across the street, Darren, was outside. I twisted the lock and threw the door open.
