A Thousand Lifetimes (en Inglés) - Chris Cathey

Francis Kowalski once told his wife, Catherine, that he would cross a thousand lifetimes just to be near her.

At the time, it was only a promise made in an ordinary kitchen, during an ordinary evening, while the water ran and the radio played. Then Catherine is murdered on Calloway Street, and Francis discovers that love can become something far more dangerous than memory.

An aerospace engineer by trade, Francis retreats into grief, obsession, and the impossible mathematics of time. In the basement of the home they once shared, he builds a machine that may allow him to send his consciousness backward into his own past. His goal is simple: return to October fourteenth, reach Calloway Street in time, and save the woman he loves.

But time does not yield easily. Each attempt costs him. Each failure leaves a mark. Each loop reveals more about Catherine, the man who killed her, the people who might have changed the outcome, and the terrible weight of trying to undo a moment the world has already accepted.

A Thousand Lifetimes is a novel about love, grief, time, sacrifice, and the question at the center of every impossible promise: how much of yourself would you spend to save the person you cannot live without?
