The Clockmaker's Royal Warrant

About this book:

In the soot-choked heart of Clerkenwell, Ada Marsh fights to save her father's legacy—one precise gear at a time. With debts mounting, the lease expiring, and the Clockmakers' Company waiting for her to fail, her only hope lies in winning a Royal Warrant for fifty marine chronometers. But the competition has just arrived in a cloud of Parisian gunpowder and ambition: Denis Lacroix, a French émigré with a dividing engine, standardized dies, and a revolutionary vision of interchangeable parts that threatens to render Ada's hand-crafted excellence obsolete.

As London fog swallows the lanes, the rivalry between the meticulous Englishwoman and the charismatic exile ignites into something far more dangerous than professional jealousy. Lacroix sees the future in iron and uniformity; Ada reads the soul of metal in the touch of a file. But with Guild wardens sabotaging innovation, a landlord circling like a vulture, and secrets from the Terror crossing the Channel, neither can afford to lose. In a world where a single second's error sinks ships, their clash becomes a race against time itself—where the winner claims the Crown's seal, and the loser vanishes into history.

*The Clockmaker's Royal Warrant* is a masterwork of historical fiction: a tense, tactile duel of wits and wills set in the workshops where longitude was conquered. For readers who love the atmospheric precision of *The Miniaturist* and the intellectual spark of *The Alienist*, this is a novel about the price of perfection, the weight of inheritance, and the fragile, ticking heart that beats beneath every great invention.
