Two friends. Ten summer trips. Their last chance to fall in love.

12 summers ago: Poppy and Alex meet. They hate each other, and are pretty confident they'll never speak again.

11 summers ago: They're forced to share a ride home from college and by the end of it a friendship is formed. And a pact: every year, one vacation together.

10 summers ago: Alex discovers his fear of flying on the way to Vancouver.

Poppy holds his hand the whole way.

7 summers ago: They get far too drunk and narrowly avoid getting matching tattoos in New Orleans.

2 summers ago: It all goes wrong.

This summer: Poppy asks Alex to join her on one last trip. A trip that will determine the rest of their lives.
