A funny, frank and genuinely helpful book about female friendship by the two women behind the hugely successful podcast Call Your Girlfriend - and the term 'shine theory'.

'Wonderful and intimate portrayal. A story is as universal as it is revolutionary' HILLARY RODHAM CLINTON

A close friendship is one of the most important relationships a human life can contain. Anyone will tell you that! But most people don't talk about what it takes to stay close for the long haul.

Now two friends, Aminatou Sow and Ann Friedman, tell the story of their messy and life-affirming Big Friendship in this honest and hilarious book that chronicles their first decade in one another's lives. As the hosts of the hit podcast Call Your Girlfriend, they've become known for frank and intimate conversations. In this book, they bring that energy to their own friendship-its joys and its pitfalls. Through interviews with friends and experts, they come to understand that their struggles are not unique.

An inspiring and entertaining testament to the power of friendship, this book will invite you to think about how your own bonds are formed, challenged, and preserved. It is a call to value your friendships in all of their complexity. Actively choose them. And, sometimes, fight for them.

'Here, friendship gets the emotional and intellectual respect it deserves; and like any truly great love story, Ann's and Aminatou's is a page turner. I love this book' REBECCA TRAISTER
