Exact it is dangerous and the kids from this book tried to obtain knowledge and power...but something went terrible wrong and things got dark very fast.
Now ... I am from Romania and my country still holds a strong position in the belief and practice of witchcraft...the belief is so strong that some events from the past actually inspired a documentary to be done...and then more and more....
Historically speaking it is rooted in the gypsy clans of Romania...but the practice, superstitions and curses were in the Romanian tradition way before gypsy arrived.
Maybe I will write little bit about this subject in a future post.
