There are two reasons for this. First, because she's around teens, she knows how to talk with them and what their interests are. The spells she includes have relate to teenage problems: finding peace at home, getting new friends, raising self-esteem. The tools for the spells are all within a teen's budget. They include such common items as eggs or potatoes, or even just a pen and paper. They'll be learning about real Witchcraft in a way that is easy, fun, and safe.
Second, because she is a mother herself, she says the kind of things that teens need to hear. For example: drugs and alcohol don't go with magick; a ritual can help build your confidence so you can remember answers for tests (but you still must study so you know the answers to put down; "Witches do not work magick to harm others and we know that no real power lies in evil." There's even a spell to help keep Internet stalkers away.
This book is filled with everything a teen needs to know to start practicing Witchcraft. It also provides guidance so that teens can continue with their studies of Wicca. Without hesitation I can recommend Teen Witch as the first book any parent could give to their teen interested in the Craft. I also recommend it to any teen who wants to learn what real Wicca is all about.
