And they're joined by new instructor Hawkeye! But tragedy strikes when a faculty member is murdered, and the killer hides in their midst! Can the new and old students band together to root out the traitor, or is the Avengers Academy's future doomed before it begins? Collecting AVENGERS ACADEMY #21-28."
