How many books do you read at the same time?

I'm reading Pride and Prejudice too, and The Book Thief, and The Page, Heart-Shaped Box and only just yesterday I finished Incarceron and I think a bit ago I finished Snow in August. The Book Thief and Snow in August are for school. I'm starting Mists of Avalon soon. I can read a lot of books, and I'm usually done quickly.
