The different lantern corps come together to defend Oa and the green lantern from the black lanterns. That's it really. A couple of minor plot lines are tied up each individual lantern member's story is advanced but since I don't really care about Kyle Rayner's love life or pointy eared chick's dead parents I wasn't too thrilled. When the black lanterns get you they talk trash and try to make you emotional, so the history of every character is brought up again and I don't care about it at all. Reading the Green Lantern Blackest Night and Blackest Night 0-8 was sufficient for me, nothing new here.
