"Guy Gardner's got a missing comrade, a red-ring-wielding Supergirl, and a deeply pissed-off Atrocitus to deal with! The last thing he needs is another new Red Lantern - especially when this one may be the deadliest Red to ever wear the ring! But whose side will this new Lantern join? And will Rankorr survive his close encounter with Atrocitus and Dex-Starr?"
