This was a lead-up to the big Blackest Night event. It's very short, and the sole purpose is to introduce Larfleeze and the Orange Lanterns. Orange Lantern, really, as Larfleeze is too greedy to allow anyone else to have an orange ring. Orange being the light of greed, you see. Considering that I read Blackest Night before I got my hands on Agent Orange, I can say with confidence that one can read and understand Blackest Night, and Larfleeze and his role there, without having read Agent Orange. Which is good, honestly, because this is one of the least inspiring of the Green Lantern collections I've read lately. If you just want to get up to speed on Darkest Night, don't bother.
