When Syd the Shiba Inu returns to Shiba Island after a ten year absence, she sets off a chain of events that overturns the lives of all the dogs she had left behind. She gets back in touch with her old friend, Max, and along the way meets a mysterious Labrador retriever named Quei-Li. (What’s a Lab doing on the Island, anyway?) They are her only remaining allies as she tries to survive the past that made her leave the Island in the first place.
