Since I've been gone... well, I can't remember EVERYTHING I read, but here's some:
"Special Topics in Calamity Physics" by Marisha Pessl -- good story, a little too wish-fulfillment-y (plain girl is adopted by popular clique), and the ending bothered me a LOT although it was in the style of the rest of the story. Not genre.
"Memories of the Future, Volume 1" by Wil Wheaton -- bought this for my dad, and finally had time to borrow his copy. HILARIOUS, but only if you like Wheaton's style. Otherwise... well, it's not a tell-all, so there's not a ton of behind-the-scenes stuff. But then, I've never been a huge BTS fan.
The entire Scott Pilgrim series by Brian Lee O'Malley -- great stuff, and I think the film made good choices in what to cut. It dragged on a bit in places, but overall I was very pleased. Plus, I got all six books for $24, which is a GREAT deal on manga-sized products.
"I Shall Wear Midnight" by Terry Pratchett -- my review is on the EP blog, but in short: I liked it.
"The Somnambulist" by Jonathan Barnes -- reading now. Kind of underwhelmed. There are SO MANY plot threads...
