The Chalon Heads by Barry Maitland: lovely mystery, 3rd in the series.
The Sea of Monsters and The Lightning Thief by Rick Riordan: a quick read, obviously playing off the popularity of the Harry Potter series but with enough original touches to be fun in their own right.
Also, I went to see "The Girl with the Dragon Tattoo" at our local second run/art house theater. If you're thinking of seeing it, GO SEE IT. Do not be put off by the subtitles... they're well done and the dialogue is slow enough that you won't miss any critical action while reading them.
