Wow, I've never posted here? Well, here goes with a few...
1984, George Orwell
Brave Story, Miyuki Miyabe (translated by Alexander O. Smith)
Coraline, Neil Gaiman
Feed, M.T. Anderson
Lies My Teacher Told Me, James Loewen
After, Francine Prose
Brave New World, Aldous Huxley
Daemon, Daniel Suarez
Scott Pilgrim (series), Bryan Lee O'Malley
Harry Potter (series), J.K. Rowling
Also, I haven't decided yet if House of Leaves is one of my favorite books yet. It certainly left quite the impression on me, though (ditto with The Raw Shark Texts). In any case, I just couldn't finish Only Revolutions, and that's rare.
