It's on my reading list so I don't know if it's exactly what you're looking for (I have a feeling it's more about general evolution) but I've heard good things about Jerry Coyne's Why Evolution is True as well as Dawkins' other books like The Blind Watchmaker, which I enjoyed, or The Selfish Gene, which I have also not read yet.
Other resources that you might think are useful or interesting:
Berkley's Evolution Site

A paper on the origin and evolution of DNA
http://www.ncbi.nlm.nih.gov/books/NBK6360/
Or you can go on Amazon and find a good, reputable author or book on evolution and use the "recommended titles" feature to find others. That's what usually gets me in trouble on Amazon.
Also, google is your friend.
