Eliot had chosen a fairly basic enchantment that created a small, softly glowing orb. Josh attempted a counterspell, muttering it half-heartedly while sketching a few cursory gestures with his large fingers. He always looked embarrassed when he cast spells, as if he never believed they were actually going to work.

But as he finished, the day went slightly faded and sepia toned, the way it might if a cloud drifted in front of the sun, or in the first moments of an eclipse.

“What the hell . . . ?” Janet said, squinting up at the sky.

Josh had successfully defended the square—he’d abolished Eliot’s will-o’-the-wisp—but he’d gone too far. Somehow he’d created its inverse, a black hole: he’d punched a drain hole in the afternoon, and the daylight was swirling into it. The five Physical Kids gathered around in the amber light to look, as if it were some unusual and possibly venomous beetle. Quentin had never seen anything quite like it. It was like some heavy-duty appliance had been turned on somewhere, sucking up the energy needed to light the world and causing a local brown-out.

Josh was the only one who didn’t seem bothered by this.

“How you like me now?” He did a victorious-chicken dance. “Huh? How do you like Josh now!”

“Wow,” Quentin said. He backed away a step. “Josh, what is that thing?”

“I don’t know, I just waved my little fingers—” He waggled his fingers in Eliot’s face. A soft breeze was kicking up.

“Okay, Josh,” Eliot said. “You got me. Shut it down.”

“Had enough? Is it too real for you, magic man?”

“Seriously, Josh,” Alice said. “Please get rid of that thing, it’s creeping us out.”

By now the whole field was plunged in deep twilight, even though it was only two in the afternoon. Quentin couldn’t look directly at the space above the metal square, but the air around it looked wavy and distorted, the grass behind it distant and smeared. Underneath it, in a perfect circle that could have been ruled by a compass, the blades of grass were standing up perfectly straight, like splinters of green glass. The vortex drifted lazily to one side, toward the edge of the board, and a nearby oak tree leaned toward it with a monstrous creaking sound.

“Josh, don’t be an idiot,” Eliot snapped. Josh had stopped celebrating. He watched his creation nervously.

The tree groaned and listed ominously. Roots popped underground like muffled rifle shots.

“Josh! Josh!” Janet shouted.

“All right already! All right!” Josh scrubbed out the spell, and the hole in space vanished.

He looked pale but regretful, resentful: they’d pissed on his parade. They stood silent in a half circle around the half-toppled oak. One of its longest branches almost touched the ground.
