Normally, this would be the part of the review in which I give a plot summary, but I don't really have a clue.
Vampires, werewolves, the witch Bathory - her of the virgin blood bathing - and more plot lines and events in time and space than is good for a comic. It would have been challenging to get it all in one novel, but this is an entirely different format. So we have a few panels, then a panel informing us of a different time and country, a few panels, next change. Too much in too little space.
I know I started reading this series about ten years ago, and that doesn't help, either.
No attachment to characters, and I felt like the author and drawer Hans Steinbach assumes you would know far too often as is reasonable.
Another problem is that every panel is overladen with details, which is good, but not everywhere we got panels around words so sometimes instead of being able to read, you have to search.
This guy needed loads of practice as he wrote and draw this.
