Set on a tiny island off the Isle of Man in 1831, Light is a family drama that reads like a pulse-pounding thriller. Sisters-in-law Lucy and Diya are raising their children together far from prying Victorian eyes, even as they dread the day the outside world will come to their island. That invasion arrives in the form of a surveyor and his assistant, sent to the remote outpost because a new lighthouse must be built and, according to custom of the time, a man must be found to replace the current lighthouse keeper, Lucy. That Lucy does a man's job and Diya turns out to be a highly educated Indian woman shocks and confuses the men, but soon romance blossoms. Faced with banishment from the only home she'd ever known, Diya's hot-headed daughter attempts a terrible act that may lead the family to ruin. With an assured eye for capturing the alien beauty of the island, Margaret Elphinstone creates an empathetic and compassionate tale of two singular women coming to terms with a sea change in their lives.
