Collects X-Men: First Class (2007) #1-5 and X-Men: First Class Special. The early days of mutant fun is back! Unfortunately, the X-Men are a male-dominated group in this early time. Concerned that star pupil Marvel Girl could use a role model, Professor Xavier enlists the world's top female hero - Sue Storm, The Invisible Girl! Also, the five young mutants take a trip to Monster Island, where they soon realize that the words "survival" and "Monster Island" just don't have much to do with each other.
