I would be interested in doing a book club on Carl Zimmer's The Tangled Bank. It would be a good excuse to pick up a copy and look through it with the idea of using it for a non-majors/intro course.
I've just got a copy of Zimmer. If there's another one or two takers, I'd be interested in making a start. (I've got a Roman history reading project going/languishing in parallel, but Zimmer is germane to my Science and Religion teaching unit...)
