Reading Cormac McCarthy's The Road. Very well-written, but... Boy, this makes the ending of Ol' Yeller look like H.R. Pufnstuf. Maybe I'll follow up by re-reading All Quiet On The Western Front and 1984. If you did that, you'd probably need to be cheered up just to commit suicide.
In other news, watched the movie Sunshine the other night. Lush cinematography ("light" is practically worthy of nomination for Best Supporting Actress), great effects, interesting story, not a physics textbook; I loved it. Think Alien meets The Enemy Stars.
