From the author of Time on My Hands: A Journey in the World of Watch Collecting comes an international mystery.

When time itself is the prize, no one plays by the rules, and brilliance doesn't guarantee safety.

A genius inventor.

A world-changing secret.

A deadly countdown.

John Harrison has spent years hidden in plain sight: an unassuming professor, a man more at ease with his dog than with people. But behind the closed door of his workshop lies an invention that could change watchmaking forever. He wants to release it freely to the world. Others want to own it, bury it, or steal it.

From Swiss boardrooms desperate to survive, to Manhattan towers built on ambition, powerful forces are moving against him. As whispers turn to threats, and loyalty becomes deadly, John finds himself at the center of a struggle he never sought.

Break-ins. Betrayals. Murder. Everyone wants his invention. No one plays fair.

Time doesn't wait. And John's is running out.

Sweeping across continents and into the secretive world of luxury timepieces, Time Eternal is a suspenseful, deeply human story of invention, obsession, and the price of genius.
