Doing my own mini-readathon tomorrow. Planning to read and/or finish:

The Selfish Gene
The History of Love
The United Nations: A Very Short Introduction
Reading the Vampire Slayer: The Complete, Unofficial Guide to 'Buffy' and 'Angel' (Reading Contemporary Television)

I might throw in some light reading (well, not counting the Buffy book) and I'm sure I will add in another title. The point of this is to get back into the habit of reading and reach my goal of 100 books this year. I might add in a novella tomorrow, too.
If I'm at home, I'll post updates as I go along.
