Star Trek/Green Lantern #1
Two iconic franchises collide for the blockbuster crossover event of 2015! The crew of the U.S.S. Enterprise meets the Green Lantern Corps for the first time in an all-new adventure that spans the cosmos! Don't miss the thrilling first chapter of THE SPECTRUM WAR, as Kirk and Spock make a most unusual discovery on a lost world... igniting events that will change the fate of empires!
This was pretty good, but not probably the best way this crossover could have started. Nothing all to unexpected happens, but it does give a nice start to the story arc.
