DeLappe's play The Wolves premiered in September 2016 Off-Broadway at The Duke at 42nd Street and received acclaim and awards.
The play centers on the experiences of high school girls through their weekly Saturday morning pre-game soccer warmups.
It received the American Playwriting Foundation's inaugural Relentless Award in 2015,[1][2] and was a New York Times Critic's Pick.
The Pulitzer Prize committee wrote: "For a timely play about a girls’ high school soccer team that illuminates with the unmistakable ping of reality the way young selves are formed when innate character clashes with external challenges.
