This book was so ridiculous that it actually made me laugh, so even just for that it totally deserves 3 stars. mind you, i'm not sure that was the effect the author had in mind, but still... :)
Another point in its favour is that it is honest, it's not written as if it were a poiem, but it just admits that it's slutty guildy pleasure reading, so another thumbs up for that.
Overall, fun read, a palate cleanser after some 'heaviver' reading, I do certainly advice you to read it if you're into this kind of novels
