At twenty-two, Y/N is determined to spend one final summer making memories before real life begins. Alongside her best friends, Liv Sterling and Theo Sinclair, she sets off on a cross-country road trip to America's most iconic national parks—armed with a trust fund, zero responsibilities, and a talent for making questionable decisions. The only problem? Vincent Monroe. Once her closest friend, now her sworn enemy, Vincent is the last person Y/N wants trapped in a car with for months. But as old wounds resurface beneath mountain sunsets, late-night campfires, and endless miles of open road, Y/N begins to realize that some people are impossible to leave in the past. A story about friendship, freedom, first loves, second chances, and the unforgettable summer that changed everything.
