Lucy lives on the 24th floor. Owen lives in the basement. It's fitting, then, that they meet in the middle, stuck between two floors of a New York City apartment building, on an elevator rendered useless by a citywide blackout. After they're rescued, Lucy and Owen spend the night wandering the darkened streets and marveling at the rare appearance of stars above Manhattan. But once the power is back, so is reality. Lucy soon moves abroad with her parents, while Owen heads out west with his father.
However, they find the brief time they spent together has left a mark. And as their lives take them to Edinburgh and to San Francisco, to Prague and to Portland, Lucy and Owen stay in touch through postcards, occasional e-mails, and phone calls. Can they, despite the odds, find a way to reunite?
