This sweeping story is set aboard the Morning Light, a Nova Scotian merchant ship sailing through the South Pacific in 1912.Kay and Thea are half-sisters, separated in age by almost twenty years, but deeply attached. When their stern father dies, Thea travels to Nova Scotia for her long-promised marriage to the captain of the Morning Light. But she cannot abandon her orphaned young sister, so Kay too embarks on a life-changing journey to the other side of the world.Inspired by a true story, Marina Endicott shows us a now-vanished world in all its wonder, and in its darkness, prejudice, and difficulty, too. She also brilliantly illuminates our present time through Kay's examination of the idea of "difference" - between people, classes, continents, cultures, customs and species.
