Picture a pathway running along the twin banks of a river so broad and majestic that it's known as «the sea», stretching all the way from Pointe Bonaventure to Natashquan, flowing past Tadoussac, then on to Anticosti and the îles de la Madeleine. This is the route of the lighthouses, a coastal highway unfrequented by visitors, and a maritime road half-forgotten by mariners themselves. In Sentinels of the St. Lawrence, Patrice Halley lets readers discover these lighthouses for themselves, in a world where sea and sky create breathtaking landscapes.
