Poppy and Alex. Alex and Poppy. They have nothing in common. And somehow, they are the best of friends. For most of the year they live far apart, but every summer, for a decade, they have taken one glorious week of vacation together. Until two years ago, when they ruined everything. When someone asks when Poppy was last truly happy, she knows it was on that ill-fated trip with Alex. So, she decides to convince him to take one more vacation together. Miraculously, he agrees. Now she has a week to fix everything. If only she can get around the one truth that has always stood in the middle of their seemingly perfect relationship. What could possibly go wrong?
