The team's lineup changes forever in the perfect jumping-on point for the series. When a dangerous alien invades Los Angeles, the Runaways' own Karolina Dean may be the only hero in the Marvel Universe who can stop him...but at what cost? Plus, the Runaways embark on a coast-to-coast adventure, guest-starring Cloak and Dagger and the New Avengers! When Cloak is accused of a crime he didn't commit by the heroes of New York City, the vigilante is forced to turn to the teenage Runaways for help - taking the teens to the Big Apple for the first time.
