Two couples, each with a twelve-year-old child, travel to Paris; within a few moments of discovering each other in a crowd, one of their children disappears. A day later, one of the mothers disappears, too. The story that follows is a wonderfully strange, beautifully composed examination of happiness and desperation, complete with a man in a bear suit, a teen pop star, and eight really excellent songs. Sheila Heti's debut play was first commissioned in 2001, for a feminist theater company that never ended up staging it. Its turbulent creation became the backdrop of Heti's last novel, "How Should a Person Be?," which was named a Best Book of the Year by the "New York Times" and the "New Yorker"--and now the play itself can be revealed at last. With new introductions by Sheila Heti and director Jordan Tannahill, "All Our Happy Days Are Stupid" offers a novel's worth of wisdom and humor, of wild hope and dreamlike confrontations, and page after page of unforgettable lines. Seen until now only by a lucky few, its publication is a cause for celebration.
