Empty?

I failed to mention yesterday that I attribute the empty feeling to having finished the trilogy of novels by Bernard Cornwell on King Arthur. I started the new non-fiction book by William Dalyrymple on Afganistan yesterday and that seems to have helped. Also had a lovely dinner with mlj last night. But is the empty feeling really because of my reading or is my reading because of the empty feeling? I suspect that may be the case. So what does that mean?
