What is "a-force"

A-Force is an ongoing comic book series published by Marvel Comics that debuted in May 2015 as a part of Marvel's " Secret Wars" crossover storyline. The series, created by writers G. Willow Wilson and Marguerite Bennett and artist Jorge Molina, features Marvel's first all-female team of Avengers. The team first appeared as part of an alternate universe during "Secret Wars" but later reemerged in Marvel's primary continuity. Described as being "decidedly feminist", A-Force has received favorable reviews from critics.
