Mary Moon explores the landscape of long-married life—the hidden hurts and disappointments that lead women to consider leaving, and the tender weight of shared history that prompts them to stay. In “Into the Light,” a wife and mother finds the idea that she might legally choose the moment of her death comforting, but how will she balance the finality of that choice against the little joys and inevitable tragedies of living? And in “Missing the Boat,” a couple on a cruise vacation share very different ideas of how to spend their days, with unforeseen results.
