Tuning the Iron Heart

About the Story

In a soot-tinged city of brass and small rituals, Etta Calder, a meticulous tuner of Concordators—wearable devices that mediate speech and temper—must perform a risky live recalibration at a family dinner. Armed with a bimetal pin, a brazing pen, and practiced hands, she wrestles a crude suppression graft free and constructs a transductive bridge to let a stubborn, fearful father speak without being silenced. The evening shifts from brittle politeness to messy, live conversation as craft meets domestic courage.

Set in a soot-sweet city of brass and steam, Tuning the Iron Heart follows Etta Calder, a meticulous tuner whose trade is the intimate work of shaping Concordators—worn machines that translate breath, pulse, and tone into social signals. The plot begins when Etta’s brother brings their father’s device to her: someone has clandestinely grafted a suppression module meant to silence outbursts. That pragmatic request opens a moral knot. Etta must decide not through lectures or tribunals but with the tools she knows best: coils, micro-valves, and solder. The narrative frames technology as a living part of family life rather than exotic apparatus; it asks what happens when instruments meant to smooth social friction start dictating what people may feel. The four tightly focused chapters move with workshop precision. A salvage foray into the old gearworks supplies physical danger and comic absurdity—pulley bones, squeaking automatons, and a chorus of metal that undercuts tension—while a measured hearing at the Tuners’ Guild shows institutional caution colliding with domestic urgency. Most crucially, a family dinner becomes the story’s laboratory: not a moral parable but a live repair, a hands-on climax in which professional skill resolves the crisis. The prose leans on sensory detail—flux smoke, the smell of citrus in rain, the grit of a jeweller’s loupe—and on the rhythms of craft. Small moments of humor and domestic inventiveness (sprocket-shaped pastries, a retired clockwork parrot) keep the tone warm-gritty rather than coldly didactic. What the book offers is an intimate, tool-forward exploration of responsibility and repair. The tension is ethical and bodily: technologies that promise calm can also postpone the necessary labor of speaking and listening. Solutions arrive through Etta’s competence and steady hands rather than through dramatic exposés; the climax is a precise, profession-specific intervention that changes how a family chooses to live with their devices. If interest lies in compact, well-proportioned storytelling that privileges procedural intelligence, tactile worldbuilding, and emotional honesty—an account of how craft acts as moral agency—this novella delivers a modest, thoughtful rumination on making, mending, and the hard work of reconnecting.
