Zero Hour 30th-Anniversary Special

30 years ago, one of the DCU's brightest heroes fell from grace, driven over the edge by his failure to save Coast City and millions of people. In the famed EMERALD TWILIGHT storyline, Hal Jordan became PARALLAX in the wake of Coast City being annihilated. After that, he almost succeeded in refashioning the entire DC timeline and resetting reality to restore his home in the ZERO HOUR event. Luckily, the heroes prevailed and destroyed this villain and timeline for good...or so we thought. Green Lantern Kyle Rayner is about to discover Hal and his vision have survived, and they're willing to do whatever it takes to make sure their world prevails!
