I read the series and greatly enjoyed it but it really started pushing who was a vampire too much. Vinyl Scratch, okay that makes sense with sunglasses and a pale coat. Photo Finish and Hoity Toity, okay again sunglasses and wearing a good amount of clothes with pale coats. Fleur Dis Lee, okay that is pushing it a bit as she she doesn't wear sunglasses and is out in the sun with nothing more then a hat.
... then Luna, ruler and protector of the night. I mean seriously, why couldn't she simply be herself and jsut support those of the night, why did she need to be one. Honestly that broke my willing suspension of disbelief.
