Lana and Cassie have met only once before, at the wedding of Lana's Grandpa Howe and Cassie's Grandma Tess two months ago. They didn't exactly hit it off - in fact, depending on who you ask, that first meeting was either an embarrassment or a disaster - but they're about to spend an entire week together, just the two of them and their honeymooning grandparents, road-tripping in Cassie's grandmother's Subaru. Lana thinks a summer road trip sounds like fun, but the backseat is a crowded place for two twelve-year-old girls with two huge secrets to hide, and this bumpy road to friendship is full of unexpected twists and turns. Like it or not, they're in this together, full speed ahead on the adventure of a lifetime.
