Manuel García never imagined that, at sixty-two, he would find himself beginning a new chapter behind the wheel of a school bus. After retiring from decades as a mechanic in a Vallecas garage and losing his wife only months later, the silence of his apartment had become unbearable.

Driving the bus, even through the sleepy outskirts of Seville, filled his days with enough motion and noise to drown the echo of grief. He liked the rhythm of it: children climbing aboard with half-tied shoes and mismatched backpacks, teenagers sighing into their phones, the familiar clatter of the engine he could diagnose by sound alone. It wasn’t glamorous work. But it kept his hands busy, his mind occupied, and his heart tethered to something steady when everything else in his life felt like it had drifted loose.

Two weeks into the school term, when the routines had settled into predictable cycles, he noticed a new passenger who didn’t quite fit into the usual patterns of childhood chaos. A fourteen-year-old girl named Lucía—small, quiet, almost ghostlike in how she moved—began sitting in the seat directly behind him.
