"An alien attack--a city warped--and Captain Marvel looking to the Avengers with murderous intent! Then, the Avengers are in chains, and their only hope lies with their greatest hero: Doctor Doom?! An army of Red Skulls threatens to overwhelm them, a cadre of bloodthirsty killers will hunt them, and even Spider-Man is out to get them! But who's behind this madness, altering the very fabric of reality over and over again?"-- Provided by publisher.
