Two flashes on the horizon. Six hours until the fallout arrives. A shelter built for six — and twenty-two children on his school bus.Sam Reyes taught nuclear survival for the Air Force for twenty years. Now he drives a rural Montana school route — and when warheads hit the missile fields eighty miles upwind, he's the only man in the county who can do the math on what's coming. The math says his basement shelter keeps six people alive for two weeks. The mirror says twenty-two kids are watching him decide.
He takes them all.
What follows is the most harrowing two weeks in survival fiction — a sealed room, a falling needle, a mother pounding on the hatch at the worst possible hour — and then the harder emerging as the one man whose meters can tell a shattered county where it's safe to live, farm, and bury its dead... just as the government arrives with a map drawn three states away, and wrong.
The finale of the When It All Falls Apart series, and its whole argument in one instruments, doctrine, and neighbors — in ascending order.
Includes "What's Real in This Book" — a plain-language appendix on fallout, the seven-ten rule, shelter that actually works, potassium iodide, and why distant nuclear war is survivable if you know the arithmetic.
