Great Prelude
While escorting Sinestro to his execution, the Green Lantern Corps is attacked by Red Lanterns and the Sinestro Corps.
I believe the function of a company wide crossover, at least in a buisness sense is to introduce readers to books they otherwise would not be reading. On that note, and all of the others, this book works. I am now very excited about this summers crossover. This is definitely one of the best things to have come out of the Final Crisis. Very exciting, and very well written and drawn.
