Critically acclaimed storytellers Geoff Johns and Dave Gibbons team with superstar artists Ivan Reis, Patrick Gleason and Ethan Van Sciver to tell the most tragic story in the Book of Oa. Once one of the most honored members of the Green Lantern Corps, Sinestro of Korugar fell to the corrupting influence of the Green Lantern's power ring, and its nearly limitless power, and was banished from the known universe for his crimes. Now, together with some of the most powerful villains from across the cosmos, Sinestro builds a new Corps. Their mission: Rid the cosmos of Green Lanterns and establish a new universal order in the galaxy-under the merciless rule of the Sinestro Corps.
