Green Lanterns, Issue #2 begins on Ysmault, the home planet of the Red Lanterns. The different colored Lanterns came about under Geoff Johns's 4000-page run on Green Lantern, continuing into the New 52. The Red Lanterns channel their rage to create power. Throughout the eight-year existence of the Red Lanterns in DC Comics, they've been complicated characters, but here, they want to create a new Ysmault, on Earth. The only people who can stop them are the Green Lanterns Simon Baz and Jessica Cruz. Jessica Cruz is new to me, but Simon Baz showed up at the end of Geoff Johns's series.
Jessica Cruz was a home-bound recluse when the Green Lantern ring picked her, saying, "you have the ability to overcome great fear." There's a great amount of this issue dedicated to Cruz overcoming her fear, developing the willpower. At the same time, there are the Red Lanterns taking over the Earth. Simon Baz was a falsely accused terrorist in Guantanamo Bay when the Green Lantern ring picked him. I've always been fond of his character, and Jessica Cruz is growing on me.
