I realize that the title is very descriptive. The point in all of Don Miller's books is the role of Story. In fact, his latest book, coming out in August, was originally going to be called Let Story Guide You, though he rewrote it and changed the title to A Million Miles in a Thousand Years.
Anyway, he gave a brief overview of the book on his blog, and laid out what he thinks is the true narrative structure of Christianity.
For more on Million Miles, see Miller's interview -- really, it's more of a video-taped conversation -- with his publisher, also on his blog.
For more on Miller himself, check out his website, his blog, or any of the many posts I've written on Miller.
