Cooper Harrison, a member of the Boston K-9 unit, never thought he would ever go back to his hometown, Harmony Farms. But when his faithful canine partner, Argos, is killed in the line of duty, Cooper finds himself mired in grief. Jobless, on the verge of divorce, and in a self-destructive rut, Cooper has little choice but to accept an offer for the position of animal control officer in Harmony Farms. And so he finds himself back where he started. Where his father, Bull, was once known as the town drunk. Where his brother, Jimmy, was a delinquent and a bully. Where he grew up as one of those Harrisons. Forced to face the past while dealing with the present--including his brother's continued involvement in the drug business--Cooper does his job with deliberate detachment, refusing to get emotionally invested in another dog the way he had with Argos. Until he finds himself rescuing a wounded and gun-shy yellow lab gone feral... Cooper never thought he'd find himself going back in order to move forward,
