Green Lantern: 1963: Redemption
by Doc Quantum, partially adapted from Justice League of America #22 by Gardner Fox and Mike Sekowsky 
Twenty years ago, Green Lantern failed to save a child from being murdered for reasons that were unclear at the time. As time has passed, Alan Scott has begun to realize that the boy would have become a very important person if he’d lived. But although he’s completely unprepared to learn the strange connection between the Green Lantern of Earth-One and the boy he failed to save, will this fateful meeting help Alan find a sense of redemption, after all?
