Book excerpt: Canine sailor Mabel, a summer resident of Islesboro, Maine, took an unauthorized ferry trip aboard the Margaret Chase Smith to Lincolnville Beach. There, Mabel visited a restaurant, made a few friends, and tasted some lobster before finally returning home. Sailors and Mainers will enjoy the descriptions of Penobscot Bay and beautiful Islesboro, and children will giggle at Mabel's adventures.
