Generally, I try to alternate between fictional books and productive books. I just finished the last book in the Hunger Games trilogy, so now it's on to a productive book I've wanted to check out for a while. https://secure.davidco.com/store/catalog/READY-FOR-ANYTHING-ABRIDGED-AUDIO-CDs-p-16177.php
It's not an audiobook, but you should add The Clean Coder to your list of productive books to read. Even though you're not a "coder," it's really more about being a professional on the job than it is about being a programmer, specifically. It's one of the best nonfiction books I've ever read!
