As with so many long-running superhero comic books, it can be tough for new readers to know where to start with the Green Lantern franchise. The good news is that there’s now a perfect option for readers wanting to dive into the world of Hal Jordan and experience the full scope of his cosmic adventures. Look no further than Green Lantern by Geoff Johns Book 1.
Whether you judge it by its sheer quality of its lasting impact on the larger franchise, Johns’ Green Lantern run has rightfully become the gold standard for Green Lantern stories. This is the run that managed to not only redeem Hal Jordan following his corruption as Parallax, but make him a more dynamic and exciting hero than ever. Through stories like The Sinestro Corps War and Blackest Night, Johns and his collaborators introduced an entire spectrum of Lantern Corps and greatly expanded the mythology fueling the Green Lantern Corps. And on top of everything else, Johns proved that Sinestro is one of the greatest villains in superhero comics.
