1993. When Kit meets Summer on the backpacking trip of a lifetime, he falls head over heels in love, certain that what they have is much more than just a holiday romance.

On returning home, Kit is confident he'll be able to find the magical girl he met. But when he follows the clues Summer told him about her life, the person he thought he knew doesn't seem to exist.

Heartbroken that she lied to him, and with no way of contacting her, Kit moves to the Suffolk coast for a fresh start. Little does he know that Summer is living just a few miles away - and is incapable of forgetting Kit too.

But as the months pass, Kit and Summer's paths never collide. Their lives move on, and a hazy, sun-drenched summer begins.

By the time they meet, will it be too late to start again?
