Are there any must reads for a solitary Wiccan that would be sold in ebook form? I know Raymond Buckland’s works are sold for the kindle and I’ve heard good things about him. Are there any others I should know of?

I’m really still very ignorant on so many things and I am dying to learn more and maybe not be so ignorant. I want to be able to discuss things with people and not ask stupid questions or say stupid things.
