When the dead get up, the guns last for weeks. The water lasts three days.

The System arrived the night after the dead did. It did not make anyone a hero. It read what people already were, off the licenses in their wallets, and reported the truth in flat capitals.

Vernon Dettmer, twenty-two years running a small city's water plant, drew PUBLIC WORKS, OPERATOR, GRADE III. People with combat classes laughed. Most of them were dead inside a month, and not one of the people drinking his water was.

Because his readout tells him what nothing else in the collapse will: the actual state of things. The chlorine left in the drums. The hours left in a bearing. The line at the top of the settlement sheet that reads STANDARD: NOT MET, and under it the number of days until that stops being a warning and starts being a body count.

His impossible move is telling people the real number.

The fuel, out loud. The food, out loud. The one number no leader wants to say: how many people the site can actually carry through winter, said to all of them, at a folding table, by lantern light.

The dead walk the fence line the whole time. They are weather. You design for them. What kills settlements is the latrine dug uphill of the water, the cut hand nobody looks at twice, the tank running dry while everyone watches the wire.

He has three days of chlorine, one old teacher, one fire captain who counts everything, and four wells standing two miles outside any fence anyone can build.

No combat class. No chosen one. No cure. The dead never get smarter, and the numbers never lie.

Book 1 of UTILITY CLASS, a five-book settlement-building apocalypse LitRPG about the man who keeps the water running, for listeners who want their survival earned in gallons, hours, and honest arithmetic.
