Just in case anyone is interested, the second book is now available.
The Deeper Questhttp://amzn.com/1780990243I haven't read it yet, but my copy should be getting here next week. Dean's approach is to present Chivalry in a modern context, in an attempt to make it accessible and relevant to today's men. The first book talks about the need for chivalry in today's world, and presents a modern code of chivalry based on the "12 trusts", which are very reminiscent of other variations of codes of chivalry, but written toward modern culture.
The second book is written as a sort of handbook for the modern-day knight, from what I hear.
