(+ a quite mature lore based on actual witchcraft _by that I mean people interested in the esoteric stuff would recognize some of their belief_ and dives into the secrets of the Nephilim _beings mentioned in the Bible. The author, Mélusine Vaglio, is very tasteful and does not hurt anyone's beliefs, which I appreciate a lot despite not being religious myself.)
There are 4 books.
