New England's foremost maritime historian Jeremy D'Entremont continues his definitive series about the storms, shipwrecks, and heroic lighthouse keepers of the region with The Lighthouses of Maine: Penobscot Bay. Twenty lights are detailed here, beginning with Matinicus Rock Light, located on a granite island at the southwestern entrance to Penobscot Bay, to Saddleback Ledge Light at the southern entrance to East Penobscot Bay. Each chapter features a treasury of historic photos and all the stories of the keepers, the storms they battled, and the wrecks they tried valiantly to save.
