'Text me when you get home.' After joyful nights out together, female friends say this to one another as a way of cementing their love. It's about safety but, more than that, it's about solidarity. A validation of female friendship unlike any that's ever existed before, Text Me When You Get Home is a mix of historical research, the author's own personal experience, and conversations about friendships with women across the country. Everything Schaefer uncovers reveals that these ties are making us, both as individuals and as society as a whole, stronger than ever before.
