Preparing for high school exams is hard enough, but at Super Hero High, even the tests are super-tough! Principal Waller keeps an eagle eye on her students, drilling them in math, science, literature-and other subjects like flying and powers! And no one wants to fail, because Principal Waller hands out detention faster than a speeding bullet. In the first-ever all ages DC Super Hero Girls original graphic novel, Supergirl, Wonder Woman, Bumblebee, Batgirl, Harley Quinn, Katana, and Poison Ivy are studying hard-well, maybe not Harley Quinn- when they are each abducted by a mysterious villain! Will the students outsmart their captor, save Gotham City, and still pass their finals?
