The best books to read are any books by, Silver RavenWolf. You cannot find a person more grounded and mystical as her. Best of all she is a mother which gives her insight with the Goddess. Just like all mothers. I absolutely reccomend all her books!
I also reccomend Green Witchcraft I and II by, Ann Moura. She has good insight with Nature.
The Witch's Bible by, Janet and Stewart Farrar is a good book for learning about Witchcraft tools. I only reccomend this book for that.
