“THE WOLVES, written by Sarah DeLappe and directed by Lila Neugebauer, is on at the Mitzi E. Newhouse Theater through January 7, 2018. In describing the play, the author herself said: “I wanted to see a portrait of teenage girls as human beings — as complicated, nuanced, very idiosyncratic people (…) who were trying actively to figure out who they were in this changing world around them.”
