This book has just enough D&D to warrant the title, but it is more of the author's experiences and thoughts on stuff than a book about the game. The D&D references usually branch off into light-hearted (in a heavy hors d'oeuvres sort of way) examinations of subjects such as spirituality, commitment, and fashion. Often funny and always witty, it definitely touches on her relationships with others: pets, co-workers, her boyfriend, random psychotic children on Big Wheels, and, especially, her mother.
What gives the book it's real charm to me, though, is that underneath all of the humor, wit, and sarcasm, there is an honest examination of self going on in it as well. If you are interested in a well-written, funny book with a little bit of "self-help" sprinkled in, then by all means, buy this book. It is good enough, smart enough, and, doggone it, I think you will like it. Any interest you have in D&D will just be the cherry on top.
