Description:
Every screen in the building says the same word: BELL.
The night before a big school board demo, Dad's whole network crashes, and Jack and John get to tag along to the creaky Old Brick Schoolhouse while he fixes it. Then the printers start printing by themselves. The intercom says good morning to nobody. And John keeps talking about the nice grandpa with the broom in the hall.
The doors are locked. The phones are dead. Somewhere in the building is a ghost who has waited fifty years for one thing, and it isn't a better Wi-Fi signal.
