What this book is about
Andrew Harlan is a Technician for Eternity—the organization that travels outside time to make 'minimum necessary changes' to history to reduce human suffering. When he falls in love with a woman from one of the centuries he monitors, he faces an impossible conflict. Asimov's standalone time travel novel is more romantic than his usual work.
