Earth's new Green Lantern, Jessica Cruz, learns that she must report to Oa and introduce herself to the Green Lantern Corps--as if learning new powers and being the new girl at Super Hero High weren't enough! Luckily, some of her new friends are willing to accompany Jessica. But when they arrive, instead of the Green Lantern Corps they find General Zod, Faora and Non. While the spacefaring girls take on this intergalactic threat, the Earthbound students are faced with their own challenge--pet-sitting Krypto! It's Kryptonian chaos across the universe!
