I'm currently reading A Dirty Job by Christopher Moore, Earth: An Intimate History by Richard Fortey, and Born to Kvetch (which I don't have handy and can't remember the author's name).
I recently finished Gods and Pawns by Kage Baker (which went way too fast, and left me craving more, so I'm thinking about going back and re-re-reading all the Company books, but the first time is really the best), and Trilobite! by Richard Fortey.
Most days, I read Dinosaurumpus by Tony Mitton, Punk Farm (I can't remember the writer's name and the book is in the kids' room), and How Do Dinosaurs Say Goodnight? by Jane Yolen. I have them all memorized, as does my 4 year old, but we have to read them anyways.
I've also got a couple books on knitting checked out, and a couple books on Asperger's, but I mostly flip through those.
