This is perhaps the geekiest book of all time. I am not enough of a geek to catch all the references, but I am married to someone who probably would, and I've absorbed some knowledge on the way. You don't have to be a geek to enjoy this book, but I imagine if you were a full on D&D type nerd in the 80s, you would get even more out of it than I did. Well-paced, good characters, satisfying resolution. The audio version is narrated by Wil Wheaton, to give it just a little more geek cred, and he did an admirable job. There's one part where he, as the narrator, has to refer to Wil Wheaton, because what would a nerdy book steeped in pop culture be without a Wil Wheaton reference. Very fun book.
