Jo Castle, Londoner and thirty-something firefighter, wants to save the world by being the opposite of Jack Reacher. She starts with care – care for her friends and family, care for community, care for the planet. Together with best friend Miranda, step-brother Mike and ex-boyfriend Robert, Jo turns a giant music festival on an island in the River Thames into the living city of Visco. Visco is a ‘carnival of care’, a radical experiment that challenges the very bedrock of capitalism. The story of its emergence, and how it overcomes the Establishment, is a ray of hope in dark times.
