You and me on Vacation by Emily Henry

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

11 YEARS 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 YEARS AGO: Alex discovers his fear of flying on the way to Vancouver. Poppy holds his hand the whole way.

2 YEARS AGO: It all goes wrong.

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