OK so I don't listen to death metal and I don't follow or know a lot about Satanism, but it doesn't matter...this book is funny! Yes, I'm sure some of the references and jokes went over my head, but I understood enough to enjoy the humor. Imagine if The Addams Family were into death metal, or the Family Circus practiced Satanism--that's what you have in this graphic novel. If you can appreciate dark humor, you'll enjoy this one.
