Who do you trust? In the wake of the superhero Civil War, outlaw Avengers Luke Cage, Spider-Man, Wolverine, Spider-Woman, Dr. Strange and Iron Fist are still fighting the good fight, joined by two new recruits: mistress of mimicry Echo and long-lost Avengers mainstay Hawkeye, now Ronin. But when the heroes uncover evidence of a secret invasion by shape-shifting Skrulls, paranoia starts to tear the team apart. Who can they trust when any one of them might be an alien monster in disguise? Which Avenger betrays the group? And can the embattled rebel Avengers survive when new supernatural crime boss the Hood targets them with an army of super-villains?
