How to Stop Time by Matt Haig

Tom Hazard has a dangerous secret. He may look like an ordinary 41-year-old, but he was born in 1581. Owing to a rare condition, he's been alive for centuries.

From Shakespeare's England to jazz age Paris and voyaging the Pacific, Tom has seen a lot, and now craves an ordinary life. Always changing his identity to stay alive, Tom now has the perfect cover - working as a history teacher at a London school. Here, he can teach the kids about wars and witch hunts as if he'd never witnessed them first-hand.

He can try to tame the past that is fast catching up with him. The only thing Tom mustn't do is fall in love.
