Vampires have an odd role to play in a supers game, something this book recognizes.
This takes one of the most iconic vampires in myth and one of the most notorious real-life killer and adds her to the Mutants & Masterminds 3.0 game.
The author gives us an interesting back story that should be familiar to most anyone with an interest in vampires. There is a new, more up-to-date backstory of her activities from 2001 and on.
The crunch part, her stats and powers are good and they look "right" to me.
There is also a template for a Bathory-lineage vampire, which is a good one to use in a game. Her PL is 12, which makes her a good threat against most supers.
I am not 100% sold on her being in a Goth Metal Band myself, but it certainly looks like it works here.
6 pages: cover art, condensed OGL statement and a lot of stuff to use in your game. You are getting a lot for your buck here.
