Lena, Filip, and Basia find a strange notebook in the school computer room, and a hidden message suggests their school is keeping a secret that has just started counting down.
Friday afternoons at the high school always felt slightly unreal, as if the building itself knew the weekend was close and had started to loosen its grip. The corridors were quieter, the fluorescent lights buzzed softer, and in the computer room the only sounds were the tap of keys and the steady hum of machines cooling down after programming class.
Lena, Filip, and Basia had stayed behind to help put away forgotten things from the storage lockers. It was the sort of boring task that usually ended with missing rulers, cracked headphones, and one or two doomed energy drinks. Basia was the first to stop. Deep between two yellowing textbooks, shoved so far back it looked forgotten on purpose, was an old brown notebook.
The cover was scuffed and dusty, but a small key had been drawn on it in faded ink, careful and strangely elegant. Lena took it from Basia and turned it over in her hands. The notebook felt heavier than it should have.
"Maybe it’s someone’s diary," she said quietly.
Filip was already pulling out his phone. "Or something way better."
Inside, the first pages made no sense at all. Lines of symbols ran across the paper in neat rows, mixed with formulas, dates, and names of teachers none of them recognized as if they belonged to another era entirely. In the margins, someone had written times, arrows, and short notes that looked less like classwork and more like directions. Every few pages there were sketches of the school: the staircase by the gym, the old library hallway, the locked door near the basement. Some drawings were accurate. Others showed corridors that did not exist anymore, or maybe never had.
Filip leaned closer, his expression changing as he followed one string of letters with his finger. "This isn’t random. It’s a code. Or a map. Maybe both."
Before anyone could answer, the lights above them flickered. Once. Twice. The room dipped into shadow and snapped back again. Lena looked up just as the nearest computer monitor, which had been dark a second earlier, filled with a single line of text:
If you are reading this note, the time has already started.
Basia let out a sharp breath. Somewhere behind them, in the locked server cabinet, something clicked.
Lena’s hand tightened around the notebook. None of them moved. Then, from the monitor, another line began to appear, one letter at a time.
