Callum met Luna a year ago during a beach trip and has been stuck on her ever since. One perfect day followed by a year of regret. Unfortunately for him, all he remembers about where she lives is a vague idea of what the North Carolina town sounds like. Fortunately for him, that's enough for his best friend Cato to hatch a plan. Together, they plot a route across the state in search of Callum's prospective soulmate.

Hina's life plan fell apart eighteen months ago when two pink lines had her trading in her Harvard scholarship and dreams of being a cardiothoracic surgeon for diapers and a dead-end job. Now, she dreams of the days she'll once again get more than a few hours of sleep, let alone put herself back out there like her mother so annoyingly pushes. With all her attention focused on her daughter, the last thing she needs is a romantic entanglement.

When Hina finds herself in the back seat of a pickup truck sailing toward North Carolina with her cousin and his dopey best friend, she wonders why she agreed to join such a ridiculous quest. For his part, as Callum gets to know the spirited girl who is helping them, he struggles with the suspicion that he might just have been wrong on that whole soulmate thing. He just needs to convince Hina before they succeed in their mission and ruin everything.

This is a coming-of-age first love story.
