Having brokered a fragile peace with his demons at last, ex-Afghan War pilot Mitch Stuart isn't in the market for redemption. But when he steps outside his comfort zone to help a stranger in a country pub, he inadvertently opens the door to the ghosts of a woman and a white dog he thought he'd left behind him. Veterinary specialist Lennie O'Donnell and her beloved dog, Pesh, are taking a break from big-city life to help Lennie's grandfather sell his old-fashioned rural clinic. Lennie has dedicated her career to healing those unable to tell her what's wrong, but Mitch is a puzzle even she struggles to solve - or completely let go.
