When he finally opened his eyes, he was back in his apartment. The bundle was gone. The box was gone. But his left ear was gone too—not missing, but transparent . If he looked in a mirror, he could see straight through to the other side of his head, and through that hole, the world looked different.

Leo, twenty-four and terminally bored, laughed. “What happens at the thirteenth wave?”

He could still hear the thirteenth wave. Quietly. Always.

And Leo listened. Not to music. Not to thoughts. To the raw, endless frequency of the universe tearing itself apart and stitching itself back together. He heard every cry for help he’d walked past. Every apology he’d never given. Every version of himself that might have been kind.

He was there for a year. Or a second. Time didn’t exist inside Wave 13.

He took it home.

The thirteenth orb was slightly colder than the others. Darker. When he held it up to the light, he swore he could see tiny figures moving inside—drowning, swimming, waving.
