With dozens of sectors in open rebellion against the Green Lantern Corps, Hal Jordan is faced with a crisis in the sector most important to him: 2814, home of Earth…as well as Ysmault, home of the Red Lanterns. Hal made a dangerous bargain with Guy Gardner, and now it’s time to pay up! Plus: Guy and the Red Lanterns take over policing Sector 2814! And you’ll want to keep reading Red Lanterns next month to see what happens to their newest member: Supergirl! *Source: dccomics.com
