Close friendships are the key to happiness - but we don't talk enough about what it takes to nurture them for the long haul. Telling the story of their own ten-year, complex, loving friendship, Aminatou and Ann share hard-won wisdom with honesty, hilarity and compassion. They've weathered life-threatening health scares, long-distance living, and one unfortunate Thanksgiving dinner eaten in a parking lot. And they know: the most important part of a Big Friendship is investing in each other again and again. This is a testament to the power of society's most underappreciated relationship and a compelling story of how it can survive, thrive and become a life-affirming bond.
