When the lights die, the contracts wake up."Paper beats pretty until pretty is true."A city-wide blackout strands Harbour City Medical Centre behind vendor-locked systems that won't budge without a remote "ack". With a public audit and grid reconnect set for 06:00, Trauma Chief Mara Vance and a night-shift crew have one job: keep people breathing-while rewriting the rules in real time. Elevators lie on battery, oxygen is rationed by maths, and a green cabinet insists on an Obedience Loop before it will move metal. So the team does what hospitals used to do: meters over menus, tape over theory, people over portals.CODE BLACKOUT is a fast, grounded medical-tech thriller about human custody over critical systems. Think The Martian-style problem-solving with Chernobyl-level stakes-told in sharp, cinematic chapters that read like a live incident log.Why you'll turn the pagesA new kind of villain: not malware but a contract clause-the "Obedience Loop"-that decides who breathes until someone clears it.Competence & heart: oxygen maths, manual islanding, LOTO, isolation pressure, lab Delta Law, a procurement team that finally ships the card in the crate.A wall that becomes policy: the night shift writes rules in big letters where hands live; the city ends up signing them.Inside you'll findelevators that bite (and how to bridge them), oxygen actuators that won't open without a clause, vacuum skids asking for a "resume ack", smoke purge versus isolation under one-voice AHJ, and a finale that makes the Rule on the Wall public record: "Bots may remind-two names sign."Perfect for fans of Michael Crichton's The Andromeda Strain, Daniel Suarez's Daemon, and Andy Weir's The Martian-readers who love authentic kit, high stakes, and people who stay calm when the room doesn't.Format & tone48 short, titled chapters; bingeable pace; PG-13 intensityAuthentic hospital & plant ops (no techno-babble you can't use in a hallway)A hopeful thriller about stewardship in public-with pens, tape, and the courage to sign your name.Rule on the Wall isn't just a motif-it's the ending.
