1372: Master Jean arrives in Lisbon an exile: a brilliant French clockmaker fleeing a war and a love who chose security over dreams. Now known as Jo o, he accepts a commission from King Ferdinand to build Portugal's first mechanical clock-a chance to master time, since he cannot control fate.
But as the gears take shape beneath the Lisbon Cathedral, Jo o discovers complexities that reach beyond bronze and iron. Isabel, the stonemason's daughter, sees past his genius to the wounded man beneath. And when he uncovers a dark conspiracy to silence the clock-one tied to secrets older than the Kingdom itself-Jo o realizes the mechanism he is building has become a symbol worth killing for.
