The Real Witches' Kitchen: Spells, Recipes, Oils, Lotions and Potions from the Witches' Hearth by Kate West is a really good book. loads of information here about herbs and healing, as well as Wicca festivals etc too.
'The Encyclopedia of Magickal Ingredients' by Lexa Rosean has been my best spell-making companion for years now. It's very straight forward, easy to naviagte, and has tons of entries. I highly recommend it.
Shamanism as a Spiritual Practice for Daily Life
by Tom Cowan
A guidebook for contemporary people who yearn to create a viable spiritual practice based on core shamanic methods and techniques and their own inherited or current religious commitments. An introduction to shamanism for newcomers, as well as a program for deepening an established shamanic practice.
Well it really depends on the kind of book that you want, theoretic? Or just plain practice?
There are many good books out there, I suggest you do some research on your own, about the topics that you especially want. What kind of healing? What moon magick? Look for the book, read previews, and reviews from other people who have read them. :) !
