Might make sense to reread [Kid Eternity] soon, as a companion to Sebastian O.
Action Comics #892 — Continuing Lex Luthor's residual-orange-lantern-fueled drive to find the source of more power. I liked the first two issues of this storyline a lot more than this one; this felt more like filler for the larger story. I like Cornell's characterization of Luthor, though, so I'll stick with it (so long as Borders keeps picking up the new issues, that is...).
Batman #702 — The second part of Morrison's R.I.P. missing chapter. It fills some gaps that perhaps weren't strictly necessary to be filled, but it's nice to get the additional detail and perspective.
Wonder Woman #602 — The new Wonder Woman continues her adventures. Not a lot to say about this one, really.
I'm also in the process of reading Batgirl Reborn, the TPB that collects the first seven issues of the new Batgirl series. A couple days ago, someone on one of the podcasts I listen to (I think it was Awesomed By Comics) likened this series to Bendis's Ultimate Spider-Man, and reading it in that light, I can definitely see that. It's got the same kind of light-hearted fun that that series has, and Stephanie's narration complements that feeling. I'm still not keen on the new costume, though; the purple....ribbing, I guess?...along the sides just looks off. I love the Lindsay Weir-esque army jacket look for Stephanie in her civilian wear, though.
