I always have a stack of books that I'm reading. I have a Kindle Fire on the way, so I will have a different kind of stack going! Here's what I'm looking at now:
Metaphors We Live By - George Lakoff and Mark Johnson
The Death of Adam - Marilynne Robinson
Imagination in Place - Wendell Berry
Nine Gates - Essays - Jane Hirshfield
American Pastoral - Philip Roth
The Creation of Feminist Consciousness - Gerda Lerner
