Craig's written a book 'Wisdom in Leadership: The how and why of leading the people you serve,' that I think is going to be a hit. http://j.mp/1IMGizS I asked him all my questions here.
When I met Craig at Nexus the book was still on the boat (except for a few advance copies that had been flown over ahead of time). But it's just about to be released by Matthias Media. Not $35 but $29.95.
