A lot of the Green Lantern mythos can be confusing (dear Lord, just imagine a time before wikis!)
This fairly recent collection of two previous independent collections (woah – confused already!) explains the “end” of Hal Jordan’s time and the origin of Kyle Rayner’s stint as the protector of Sector 2814.
Jordan’s rage-infused attack on Oa after the destruction of Coast City is, frankly, more exciting as told in flashbacks in forthcoming books than it is here (except for when he fights Kiliwog.) The Rayner stuff, however, is pretty cool. Did you know he was wearing a Nine Inch Nails T-Shirt when Ganthet be-quested him his Power Ring? (Yes, you now know one of the awesomest, geekiest bit of bar trivia in the Galaxy.)
