Stranded in a Dark Sector with no rings and no backup, John Stewart is out of options, his back against the wall. After the Central Power Battery dies, John must live long enough to gather the surviving Green Lanterns and find a way home, while one of the newest Green Lanterns, Far Sector's Jo Mullein navigates a host of unknown dangers on the Green Lanterns’ homeworld of Oa, as she works to uncover the cause of the battery’s collapse and who was behind it.
