Mia and Lorrie Ann are lifelong friends: hard-hearted Mia and untouchably beautiful, kind Lorrie Ann.

While Mia struggles with a mother who drinks, a pregnancy at fifteen, and younger brothers she loves but can't quite be good to, Lorrie Ann is luminous, surrounded by her close-knit family, immune to the mistakes that mar her best friend's life. Until a sudden loss catapults Lorrie Ann into tragedy: things fall apart, and then fall apart further – and there is nothing Mia can do to help. And as good, kind, brave Lorrie Ann stops being so good, Mia begins to question just who this woman is and what that question means about them both. A staggeringly arresting, honest novel of love, motherhood, loyalty, and the myth of the perfect friendship that moves us to ask ourselves just how well we know those we love, what we owe our children, and who we are without our friends.
