Merry meet @maggie79,
I’m Bry, one of the moderators here in the forum- wishing you a very warm welcome! 
I second Amethyst’s suggestion about the Courses- they are amazing resources when it comes to learning about magick! 
For literature and books in particular, there is a list of recommended books for Wiccans that you might be interested in. The list can be found here:
You are also warmly invited to come check out the Spells8 Book Club- there have been so many magickal books reviewed and shared by coven members since the club got started (and next session starts tomorrow!)
Here is a Masterlist of Book Reviews and Discussions. It’s a good place to scroll and browse to see if any books catch your eye 
Make yourself at home here, Maggie! Wishing you all the best with your magickal studies 
Blessed Be!
