After a messy divorce, Abbey Lewis accidentally becomes a pet detective, and suddenly she finds meaning in looking for people's lost pets. Her searches along Highway 4 and her interactions with three very different pet owners - one charmingly attractive, one amusingly terrifying, and one unsettlingly withdrawn - give her time and reason to examine her own life, too. Not all that is lost can be recovered. But she never gives up, and her remarkable resilience is on display again and again as she finds ways to face the risks of loving, of truth-telling, of going out and actually living.
