Enjoying Maine's Islands
This guidebook takes travelers to all the Maine islands that are accessible by public ferry. In addition to travel advice on planning around ferry schedules, packing enough warm clothing and when not to bring the dog, the book discusses the history, lore and legends of the islands. Note: A highly-recommended book about the Maine coastal region is Frommer's Maine Coast.
