I usually have an "upstairs" book, and a downstairs book that travels with me if I go to the gym. I sometimes have three or four books, all in different assigned areas.

I also recently finished:

Freedom's Ransom (by Anne McCaffrey - not a dragon one, though!)

Deepsix by Jack McDevitt - cool more sciencey sci-fi, far future stuff, very good

and

A Story for Bear - wonderful, wonderful, wonderful new children's book.
