I've read this book cover to cover over 50 times since the first time I've received it as a christmas gift in 1999. This is a quint essencial book for any fan of the show. It has all sorts of good things inside ranging from back stories on certain demons, character bios, even the love triangles on the show. My favorite parts are the explanations of the sets, how the make-up is done, and loads of other cool facts. It's my all time favorite BTVS book.
