DC Super Hero Girls Vol 4: Past Times at Super Hero High by Shea Fontana
My rating: 3 of 5 stars
This is my favourite in the series. From start to finish it is one big long story arc, with winding paths along the way. The book opens to what I immediately compare to a "Magic School Bus" episode, with the time-travel schoolbus waiting for the students to board so they can travel back to the Jurassic era. Everything goes well there until Harley decides to abscond with a pterodactyl egg and secrete it home. But when they arrive home, the world has been changed. Vandal Savage is the principal and he has laid claim to Conqueror of Earth. Everything else is different in degrees of bad. So the field-trippers go back in time and hit up a whole lot of time periods before they finally get back to Jurassic to put the baby pterry back into his nest.
