DC super hero girls (Shea Fontana)

'Intro to Epics' is one of Wonder Woman's favorite classes at DC Super Hero High, but even for an overachiever, balancing high school literature assignments with learning to be a superhero can be tough. But you know what they say about learning-experience is the best teacher! So when Wonder Woman, Batgirl, Supergirl, Bumblebee, Poison Ivy, Katana, and Harley Quinn fight a cyclops, a witch, and a bevy of sirens, they're sure to learn a thing or two...

"The students of Super Hero High go on a one-of-a-kind field trip that will allow them to learn about the past, up close and personal! In fact, they will be in the past! After a time-machine mishap, Harley Quinn, Wonder Woman, Supergirl, Batgirl and company find themselves in the Jurassic period! But how will their time in the past affect their future?"--Amazon.com.

Batgirl, Wonder Woman, Supergirl, Green Lantern, Bumblebee, and Zatanna are continually late to class because of their crime-fighting, so they must join after-school clubs to avoid being suspended and revealing their secret identities.
