The Clockwork Apprentice of Gearheart City
A Shōnen Manga About the Boy Who Repairs Living Machines

About this book:

In the soot-choked canyons of Gearheart City, every gear has a voice—and fifteen-year-old Ren is the only one who can hear them. While the aristocracy in the gilded Upper Ward treats the city’s sentient machines as disposable tools, Ren repairs their hearts with a touch and a tuning fork, hearing the difference between a stripped bolt and a dying soul. But when a monstrous construct tears into the Lower Ward’s vital junction engine, Ren discovers a nightmare forged in the nobles' laboratories: artificial parasites that twist living metal into mindless killers. Now, with the Grand Duke’s elite hunters kicking down his master’s workshop door, Ren must flee into the steam-drenched underbelly of a vertical metropolis, carrying the only proof of the conspiracy in a cracked brass cylinder.

Hunted by precision-marching automata and haunted by the screams of dying engines, Ren descends through twenty-six chapters of escalating danger—from the Rusting Heart of the Smog Drains to the Phantom Gear of the Silent Clocktower. He’ll face rival mechanics, rogue titans, and the Clockwork Curse rotting the city’s core, all while mastering a resonance that could heal Gearheart’s iron heartbeat or shatter it forever. Master Corvus taught him to turn bolts; the machines taught him to listen. But to survive the Mechanical Uprising and reach the Gearheart Core, the apprentice must become the one thing the Upper Ward fears most: a mechanic who refuses to let the voiceless be silenced.

*The Clockwork Apprentice of Gearheart City* is a high-octane shōnen adventure where *Fullmetal Alchemist* meets *Mortal Engines*—a steel-soaked coming-of-age tale packed with pulse-pounding action, intricate steampunk worldbuilding, and a hero who fixes the world one heartbeat at a time. If you crave sentient machines with souls, conspiracies written in oil and blood, and a boy who talks to iron, step into the smog. The city is calling.
