Something is wrong in Sector 2814, and Hal Jordan, Kilowog, and other Lanterns must find the mysterious disturbance despite a ban on any of Earth’s Green Lanterns leaving their world and Sinestro find themselves at the heart of it in Knight Terrors: Green Lantern. What they discover is a planet controlled by a familiar face—the face of Hal’s greatest fear! And, in a backup story, Sinestro finds himself thrust into a new reality that drags him into the darkest corners of his past and perhaps his future.
