Leah Jackson is miserable and in detention. This is particularly infuriating because the detention means she's likely to be late for her ''fame and fortune'' interview, one of the few chances kids at YOP schools have to make it into college and to get a life worth having. But Leah's worries are about to become much, much more immediate. Year 9 kids storm into the room. They're armed. And they're shooting. Leah escapes the melee by hauling herself up into the roofspace. But only just. Kids are dead. Teachers are dead. Everyone else is rounded up in the gym. Only Leah and Anton are free, but they are trapped above the ceiling tiles.
