Tomorrow was beautiful once, and it could be again. But Jack can only choose one future…

England, 2150. Time travel has accelerated climate change and set humanity on the brink of destruction. As a Person of Mixed Era Origin with the ability to recall parallel versions of time, British historian, Jack Elliot, seems the perfect candidate to travel to the past and prevent the advent of time travel.

The catch? Success means Jack will cease to exist.

Critically injured when he arrives in the past, Jack’s life is saved by Maddie, a second-generation immigrant and resistance fighter, who mistakenly believes he’s connected to the disappearance of her sister, Suraya.

Jack’s denial soon unravels with the discovery that Suraya can lead him to his father — the man who robbed him of his mother — and the inventor of time technology.

What begins as a fragile alliance soon puts their feelings and their missions to the test. Jack’s won’t be the only life affected by his sacrifice, but does he have the right to decide who should live and who should die — and will it be worth it for the futures he and Maddie hope to create?
