When Olivia Laing moved to New York City in her mid-30s, she found herself inhabiting loneliness on a daily basis. Increasingly fascinated by this most shameful of experiences, she began to explore the lonely city by way of art. Moving fluidly between works and lives --- from Edward Hopper's Nighthawks to Andy Warhol's Time Capsules, from Henry Darger's hoarding to David Wojnarowicz's AIDS activism --- Laing conducts an electric, dazzling investigation into what it means to be alone.
