Darcy believes in love at first sight.

Even though it's never happened to her, she's spent her whole life waiting for that perfect, magical moment. But right now, her life is anything but perfect. In the aftermath of a music festival, she's stranded at a bus station until morning--the day before she leaves for college. Her phone is dead, she has no cash, and she's convinced nothing good can come of this night...but then she meets Russell.

Russell. Cute and nice, funny, and kind. She knows this is the moment--and the guy--she's been waiting for. And they have until sunrise to walk and talk and connect.

Over the course of this one fateful night--filled with football field picnics, night swimming, and escape-artist dogs--Darcy and Russell's lives will change forever. They'll discover things they never imagined about each other...and about themselves.

But can you really know someone after only a handful of hours? Is it possible to fall in love in just one day?

And is it worth saying hello...when you know you're destined for a goodbye?
