Scott Lang, better known to superhero fans as Ant-Man, has moved to New York City with his teenage daughter to take advantage of some job opportunities in the tech field. If you only know Ant-Man from the Marvel Cinematic Universe, there are a few differences in this book, but nothing that is insurmountable.
Scott Lang's criminal past comes back to haunt him when a former partner in crime breaks out of prison. People connected with his conviction are dying all across the country - and the FBI thinks that Scott Lang is next. Why? Because Lang testified against him in the plea deal that turned him away from a life of crime.
Lang knows that he doesn't really need police protection - after all, he is a superhero. But, he can't tell the FBI that.
Meanwhile, his daughter is having typical "mean girl" problems with a classmate when it occurs to her that she knows where her dad keeps his Ant-Man suit and she has the combination to the lock.
