Our best friends, Twitter followers, gal-pals, bromances, Facebook friends, and long distance buddies define us in ways we rarely openly acknowledge. But as a society, we are simultaneously terrified of being alone and already desperately lonely. We move through life in packs and friendship circles and yet, in the most interconnected age, we are stuck in the greatest loneliness epidemic of our time. It's killing us, making us miserable and causing a public health crisis. Increasingly, we don’t just die alone; we die because we are alone. What if meaningful friendships are the solution?

Journalist Kate Leaver believes that friendship is the essential cure for the modern malaise of solitude, ill health, and anxiety and that, if we only treated camaraderie as a social priority, it could affect everything from our physical health and emotional well being. Her much-anticipated manifesto, The Friendship Cure, looks at what friendship means, how it can survive, why we need it, and what we can do to get the most from it. Why do some friendships last a lifetime, while others are only temporary? How do you “break up” with a toxic friend? How do you make friends as an adult? Can men and women really be platonic? What are the curative qualities of friendship, and how we can deploy friendship to actually live longer, better lives? From behavioral scientists to besties, Kate draws upon the extraordinary research from academics, scientists, and psychotherapists, and stories from friends of friends, strangers from the Internet, and her “squad” to get to the bottom of these and other facets of friendship. For readers of Susan Cain’s Quiet and Elizabeth Gilbert’s Big Magic, The Friendship Cure is a fascinating blend of accessible “smart thinking,” investigative journalism, pop culture, and memoir for anyone trying to navigate this lonely world, written with the wit, charm, and bite of a fresh voice.
