Two weeks on the road... stuck in a car with your high-school enemy.

Noelle Shepard is grieving the loss of her beloved grandmother when she discovers decades-old photos and letters that hint to a forbidden love in her gram's past. Needing to know the full story, she creates a TikTok video appealing for information - and it goes viral.

Through her video, she manages to track down her grandmother's secret love, Paul, who offers to take her on the honeymoon road-trip he and Gram planned but never got to go on.

Noelle jumps at the chance to make this one last connection with her grandmother. There's just one problem - Paul's grandson is Noelle's frustratingly handsome high-school rival Theo.

And Theo has to come, too.

It's only two weeks. Surely Noelle can survive that long? But with one car between them - and often only one bed - it doesn't take long for things to heat up...
