Something has gone wrong at Timeschool. Clocks fall out of sync. Corridors lead where they shouldn’t. Students begin to vanish — not erased, but misplaced. Zak and his friends uncover a secret buried deep beneath the school: Captain Dimension, a living experiment trapped between realities, created to stabilise time… and quietly breaking it. As Timeschool’s authorities scramble for control, Zak faces a choice that will change him forever — step back into safety, or step forward into the fracture. Because once you cross the line, time notices.
