What does it mean to be lonely? How do we live, if we're not intimately engaged with another human being? How do we connect with other people? When Olivia Laing moved to New York City in her mid-thirties, she found herself inhabiting loneliness on a daily basis. Fascinated by the experience, 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, illuminating not only the causes of loneliness but also how it might be resisted and redeemed.
