1979. Fifteen-year-old Aurora Taylor's single mother prefers to leave when things get hard. She's spent years abandoning bad boyfriends and dead-end jobs, without so much as a glance in the rearview mirror. After fifteen years in the passenger seat, Aurora needs more than two hands to count the towns she's lived in. She's learned to live small--it's easier to leave when you don't need to say goodbye. So when her mother, Laine, shows up at school with the car loaded, Aurora assumes her latest fling has run its course. Instead, it's her grandpa Jay's death calling them back to the town Laine has spent fifteen years running from.

Every visit to Monroe, Indiana, ends in an explosive fight. Her mother and her Gran are oil and water, and it doesn't take Aurora long to realize Gran has fallen off the wagon--again. With Gran drinking and Laine's discomfort in the little blue house, Aurora gives their visit a week, tops. But when Laine begins an affair with the town's married mailman, everything changes. While her mom falls in love with a man she can't have, Aurora has time to fall in love with the town. Her life begins to feel full--she has a friend to call her own, a gran who loves her, and a picture-perfect pastor's son who sees Aurora as more than "Laine's daughter." It's everything she never let herself dream about.

As the summer months march on, and her mom's happiness becomes even more dependent on her unstable new relationship, Aurora worries the dream she allowed herself will end in heartbreak. This isn't just another map dot on their endless journey, and Laine won't just burn a bridge this time. Her choices threaten to light the town on fire, burning Gran's hope, Aurora's future, and her own chance at redemption to the ground with it.
