Autumn on the Maine coastline: red leaves, hot apple cider and ... a dog playing with a porpoise? That’s life for Lars and Bangor, a dog and harbour porpoise, best friends in the town of Ogunquit, Maine. They went viral after Bangor was separated from his pod, and it was up to Lars and his human, Natalie, to reunite Bangor with his family. Now Bangor, and his pod are back, but they’re not the only visitors in town: Ogunquit has been overrun with tourists and reporters eager to catch a glimpse of the famous friends. And to make things worse for Lars, an otter named Marina has captured everyone’s heart—including Bangor’s! As Marina takes centre stage, can Lars learn to share the spotlight? And will Lars and Bangor’s friendship be jeopardised?
