"Starfire has always wanted to be better friends with her sister, who mostly comes to Earth to cause trouble instead of enjoying the sisterly bonding. But this time, Blackfire's not even in the same Earth dimension! The Teen Titans will have to go undercover in a strange new version of Metropolis...one where the heroes have secret identities! Meanwhile, the DC Super Hero Girls have all been assigned exchange students to show around school. They'd really rather battle the new super-villain in town, but hiding their super-activities from the rather strange new people staying in their homes is proving difficult."--Provided by publisher.
