Not my cup of tea- or should I say, cup of poison? 
That being said, while I’m certainly not an advocate of Baneful Magick, I don’t think there’s anything wrong with educating oneself about it 
To the best of my memory, no one has read a book about Baneful Magick in the Book Club, but I would check out the Books Tag and perhaps check out Baneful/Black Magic Discussions in the forum to see if anyone has mentioned any books about it.
I think it is wonderful that you are exploring your heritage, Nikita! I remember there was a discussion a while back with some resources that may be helpful for you:

Good luck with your studies!
