It’s New Year’s Eve, the holiday of forced fellowship, mandatory fun and paper hats. While dining out with her husband and their friends, Binnie Kirshenbaum’s protagonist --- an acerbic, mordantly witty and clinically depressed writer --- fully unravels. Her breakdown lands her in the psych ward of a prestigious New York hospital, where she refuses all modes of recommended treatment. Instead, she passes the time chronicling the lives of her fellow “lunatics” and writing a novel about what brought her there. Her story is a hilarious and harrowing deep dive into the disordered mind of a woman who sees the world all too clearly.
