If a teacher catches me in the auditorium, I’ll say I was taking photos for the school paper. Even though all the clubs have ended for the year …

And I never worked for the paper.

I push open the auditorium doors and step inside. The theater is huge, with a high ceiling and heavy red curtains that hide the stage from view.

Suddenly, I realize why the tap-tap-tap has led me here. Every school has stories. Ways to explain that creaking sound in the boys’ bathroom, that cold spot at the back of the English room, the smell of smoke in the auditorium.

My school’s the same. The only difference is that when I hear a ghost story, I get to find out if it’s real. Most of the time it’s not.

A creaky sound is just a door with bad hinges.

A cold feeling is just a draft.

But as I follow the tap-tap-tap down the theater aisle and up onto the stage, I know there’s something to this particular story.

It’s the one about a boy who died in a play.

Apparently, a long, long time ago, when the school first opened, there was a fire in the second act of A Midsummer Night’s Dream. The set went up in flames, but everyone got out—or so they thought.

Until they found the boy under the trapdoor.

Jacob shivers beside me, and I roll my eyes. For a ghost, he scares so easily.

“Have you ever thought,” he says, “that you don’t scare easily enough?”

But I scare just as easily as anyone. Believe it or not, I don’t want to spend my time searching for ghosts. It’s just that if they’re there, I can’t ignore them. It’s like knowing there’s someone standing right behind you and being told not to turn around. You can feel their breath on your neck, and every second you don’t look, your mind just makes it worse because in the end, what you don’t see is always scarier than what you do.

I climb onto the stage, Jacob at my heels. I can feel him hesitating, his own reluctance dragging me back as I pull up a corner of the heavy red curtain and slip backstage. Jacob follows, passing straight through the curtain.

It’s dark here—so dark it takes a second for my eyes to adjust to the various props and benches scattered across the stage. A thin ribbon of light comes from beneath the curtain. It’s quiet, but there’s an eerie sense of motion. The faint groan of sandbags settling on their hinges. The whisper of air beneath the floorboards. The rustle of what I hope is paper and not rats.

I know that some of the older kids in school dare each other to go back here. To put their ear to the floor and listen for the boy who didn’t make it. I heard them bragging about it once in the hall, how long they’d each lasted. One minute. Two. Five. Some claim they heard the boy’s voice. Others say they smelled smoke, heard the footsteps of fleeing children. But it’s hard to know where the rumors end and the truth picks up.

Nobody dared me to come here. They didn’t have to. When your parents write books about paranormal activity, people assume you’re weird enough to go on your own.

I guess they’re right.

I’m halfway across the darkened stage when I trip over something and stumble forward. Jacob’s hand shoots out to catch me, but his fingers go through my arm, and I bang my knee on the wooden floor. My palm smacks hard, and I’m surprised when the floor bounces a little, until I realize I’m on top of the trapdoor.

The tap-tap-tap grows more insistent under my hands. Something dances at the edge of my sight: a thin gray curtain caught in a constant breeze. Different from the heavy red stage curtain. This one, no one else can see.

The Veil.

The boundary between this world and somewhere else, between the living and the dead. This is what I’m looking for.

Jacob shifts his weight from foot to foot. “Let’s get this over with.”

I get back to my feet.

“Ghost five,” I say, for luck. A ghost five is like a high five for friends who can’t really touch. It’s basically just me putting out my hand and him pretending to hit it, both of us murmuring a soft “smack” sound on contact.

“Oof,” says Jacob, pulling his hand away, “you hit too hard.”

I laugh. He’s such a dork sometimes. But the laughter makes space in my chest, clears out the fear and nerves as I reach for the Veil.

I’ve seen people on TV—“ghost whisperers”—talk about crossing over, connecting with the other side like it’s flipping a switch or opening a door. But for me, it’s this—finding the part in the curtain, catching hold of the fabric, and pulling.

Sometimes, when there’s nothing to find, the Veil is barely there, more smoke than cloth and hard to catch hold of. But when a place is haunted—really haunted—the fabric twists around me, practically pulling me through.

Right here, right now, it dances between my fingers, waiting to be caught.

I grab hold of the curtain, take a deep breath, and pull.
