Nevertheless the story's depiction of the witches is not free from representation in popular TV series. The witches control the weather, ignite flames, get inside your mind, and can destroy. I believe that the entertainment industry of course needs spectacular scenes, breath taking adventures, extraordinary characters. This could be the reason why the witches are presented in a such an "out of this world" way.
What I like about Blake's writing is that she has that witty irony through out the narrative. You can go by the extracted lines I gave in the very beginning of this post - messing up Beltane cookies? Oh my, that could be a catastrophe! But the author makes it feel like an ordinary thing (like burning an oatmeal cake), because it is such for her characters, and there is no exaggeration of the life of a modern witch.
"Anna Dressed in Blood" contains not only witches but also warlocks, one of them is a Cas's schoolmate, another - this schoolmate's granddad, who actually passed on the witchcraft skills to his grandson. So these two and Cas's mother make a magical team who fights with a powerful soul of an obeahman. There was also a good educational moment for me personally as I never knew who that was and had to read about it in the net. For me this novel was a novelty, a fresh insight into the modern witchcraft and a nice free from judgement depiction of what witches do or what they don't.
