In the ultimate act of revenge, Sinestro, Green Lantern's greatest foe--and disgraced former leader of the Green Lantern Corps--programmed his own essence into thousands of counterfeit versions of the power rings worn by the GL Corps, and scattered them across time and space, where they've existed in a dormant state for centuries. Now those rings, and the unwitting Sleepers who wear them, have been activated, and Sinestro's all-consuming evil is about to reemerge.
As the omnipotent and omnipresent Spectre, Hal Jordan clearly sees the impending doom but, as the Spirit of Vengeance, is admonished by his higher power not to act. However, the smallest flicker of the hero Jordan once was remains within. He rejects the warning and moves to stop Sinestro's revenge. As a result, Hal is stripped of the Spectre's vast powers and cast down to earth--a powerless, disgraced mortal who has seen a glimpse of the devastation to come. Now lacking resources, friends, and credibility, Hal Jordan must start his journey from the very beginning.
In an epic finale that spans centuries, Jordan, once the greatest of all Green Lanterns, crosses time and space to destroy the Sleeper rings as Green Lanterns of the past and present--and a mysterious GL of the future--converge to save Hal from repeating his past mistakes.
Ultimately, fellow Green Lanterns Kyle Rayner and Alan Scott are the only heroes who will rally to Hal's side. But will they be too late to save the Universe? And can they prevent the greatest Green Lantern in history from, once again, becoming consumed by the very evil he seeks to destroy?
