The Light Between Oceans is a simple yet almost ingeniously original tale about, as the book's blurb has it, 'right and wrong, and how they sometimes look the same'. Set in 1920s Australia, it is the story of Tom Sherbourne, a solitary war veteran turned lighthouse-keeper, and Isabel, his young wife.
In the deep sea, the ocean is dark. That is because there is a limit to the depth of ocean that light can enter. At about 656 feet (200 meters), there isn't much light, and the sea is totally dark at about 3,280 feet (2,000 meters). To some extent, the ocean also reflects the color of the sky.
