Although not yet 40, two-time Pulitzer finalist Sarah Ruhl has established herself as one of America's most innovative and productive playwrights. She is known for charting complex currents of desire and broaching weighty topics such as bereavement with a light, whimsical touch. This critical volume represents the first full-length, comprehensive study of her work. The text tracks the evolution of her style and aesthetic, situates her body of work within the American theatre scene, investigates her influences, and analyzes her plays in depth, including Eurydice, The Clean House, Passion Play, and In the Next Room or the vibrator play.
