I can't imagine why ANY book on evolution would mention theology, any more than a book on, say, molecular biology would.

Are you after a popular science account or a serious textbook? If the latter, I'd recommend "Evolution: A Biological and Palaeontological Approach" by P. Skelton (Prentice-Hall). It's an excellent introductory text, and is very reasonably priced, too. This was the textbook I used on a distance-learning course and I found it excellent.
