One perfect day can change everything.

On a sunny May morning, Nick Tremblay is stuck at Central Maine Memorial Hospital. He's there for yet another test, this time to see if the rare cancer he's been battling for years is responding to an experimental trial. Down the hall, Ava Adler lies in an MRI machine after a concussion ended her lacrosse season. Nick and Ava barely know each other, but when they run into each other in the hospital lobby, fate has other ideas...

Determined to make the most out of a bad day, Nick convinces Ava to skip school and participate in a town tradition: finding the hidden waterfall that can make any wish come true. What begins as a spontaneous adventure turns into something deeper as Nick and Ava zigzag through their lakeside town, chasing clues and sharing their favorite places. When the sun begins to set, the feelings between them become impossible to ignore-but how can you fall for someone when you know your time is running out?
