The morning sun has left everyone sun-kissed and pleasantly exhausted after hours of splashing in the waves and playing beach volleyball.

You're about to follow when something catches your eye—Hannah is still down by the water's edge, completely lost in her own little world as she meticulously shapes towers and walls into what's becoming an impressively elaborate sandcastle. Your heart does that familiar little skip it always does when you watch her get so absorbed in something that captures her interest.
