I try to maintain a policy of carrying at least 2 books in my bag at all times. This is a preventative measure in case I finish one of them while out somewhere. Lately I've been trying for one nonfiction and one fiction title.
Current books in my bag are:
Dois anthology which I mentioned in another entry.
and
Waiting for the Barbarians by J.M. Coetzee which is kind of reminding me of Camus in subject matter and style but with less economy of words and more sex. I like it.
