Beginner witchcraft books for non wiccan witch?

You're not going to find many books on witchcraft that arent wiccan...although with those all you have to do is sift through the redundant moralizing over the why to get to the what. A book called the magic power of witchcraft by Gavyn and Yvonne frost is a good book to start with. As far as runes well...Edred Thorsson is your best source for information on runecasting and with rune magic, followed closely by Kveldulf Gundarsson and Freyja Aswynn. Most other books on the subject are just reworkings of those three authors.
