Darkness envelops the DC Universe, as the aptly named alien known as the Sun-Eater plunges the Earth into permanent night-and along with it, freezing temperatures and ecological disaster. Can DC's greatest heroes and scientists save the day? And what does this mean for Superman, whose powers are derived from Earth's sun? With hope all but lost, can Hal Jordan save a planet he previously turned his back on? And if so, at what cost? Collects The Final Night #1-4, Parallax: Emerald Night #1, Green Lantern #81, and The Final Night Preview #1.
