Emma Turner is thirty-eight, divorced, and certain that great love happens to other people.

Then the letters begin.

Every year on her birthday, a handwritten envelope arrives with no return address — predicting small, specific moments before they happen. A coffee spill. A blue jacket. A choice that will change everything. Each prediction comes true. Each letter is signed the same way: Your Husband.

The man writing them is named Jack. He is eighty-two years old, grieving, and living thirty-one years in Emma's future. When scientists accidentally discover a narrow crack in time — just wide enough to send ink backward across three decades — Jack uses every letter he has left to reach the woman he lost too soon, to guide her toward a better life than the one illness took from them the first time.

But changing Emma's future means changing Jack's past. Every letter reshapes the timeline. Every choice has a cost. And the closer Emma gets to finding the young man she is fated to love, the more she realizes: the version of Jack who wrote the letters may cease to exist if she succeeds.

Tomorrow, I Loved You is a sweeping, time-spanning love story about devotion, sacrifice, and the impossible courage it takes to love someone enough to let them go — and love them again anyway.
