Phoenix does not run out of water. It runs out of the ability to move water to the right place, at the right pressure, at the right hour — and Nadia Reyes has already watched what that looks like.

Carla Ackerman gives her hydrologist a second run at one week. In the first, pressure, power and public trust crossed a line together; hospitals lost service in an order Nadia can still recite; a private operator kept its own system running while whole neighbourhoods went dry; and her seventeen-year-old daughter died on the concrete outside a distribution gate, waiting for water that never came. Then Nadia wakes eighteen months earlier, in a cold conference room, on the morning she approves the emergency plan that helped shape all of it.

Foreknowledge works, at first. She stops a shutdown, moves supplies, forces officials to look at risks they have been deferring for years. But her memory is one exhausted survivor’s memory of one corridor of a failing city, and every correction relocates the failure: a district that survived before loses pressure early, a pump station four hundred feet uphill loses suction on the hottest afternoon of the year, a man she filed away as a profiteer turns out to control equipment the city may not survive without. By the time the week arrives she has spent nearly everything she came back with, and one certainty is left — Roy Castellan helped decide who would go thirsty. Keeping thousands alive may mean leaving him in control for six more hours.

The interest here is mechanism. Compound failure across water, power, treatment and trust is worked out step by step, with an operations chief, a public health officer, a plant engineer and a security supervisor who are all good at their jobs, and a seventeen-year-old who is right about her mother more than once. Nobody wakes up with perfect knowledge and wins. There is no wasteland, no warlord, no bunker.

That makes it a fit for readers of infrastructure-minded near-future fiction and procedural disaster thrillers — anyone who would rather watch a system fail credibly than watch civilisation collapse offstage. It runs 395 pages as Book One of The Scarcity Line and resolves fully; The Fallow Count and The Priority Date follow. Content note: heat injury, medical crisis, and the death of an adult character.
