On Radio 4's Today programme they got the people who run a website review of children's books to look at it. They were not overly impressed. It seems to be sold purely on hype.
As I stated before what parents do not realise is that JKR used
real Witchcraft from her university thesis in the books. Also some of the concepts used come from
real black magic that practicing wiccans steer clear of.
This is the promotion of witchraft and the occult packaged in "a good read" (not quite that according to the reviewers this morning). Do you want children to get dragged into that world ?
