One moment in time can change everything... The day Scarlett dies should have been one of the most important of her life. It doesn't feel fair that she'll never have the chance to fulfil her dreams - all because she stopped to help a stranger.

And now, she's still ... here - wherever here is - watching the ripple effect of her death on those she loved the most. Evie cannot contemplate her life without Scarlett, and she certainly cannot forgive Nate, the man she blames for her best friend's death.

But Nate keeps popping up when she least expects him to, catapulting Evie's life in directions she'd never let herself imagine possible. If you could go back, knowing everything that happens after, everything that happens because of one choice you made, would you change the course of history or would you do it all again?
