I felt that Seeing in the Dark was a decent introduction to shamanic practices. The author provides you with basic techniques for shamanic journeying, acquiring familiars and power animals, and she also provides the reader with instructions for constructing and using a medicine wheel.
It should be noted that this is a basic introduction to neo – Shamanism and is not based in any particular tradition. If you’re interested in Shamanism and you don’t know where to start, this may be the perfect book for you. It’s well-written and easy to understand, and it doesn’t require any prior knowledge of the subject in order to start working with the techniques.
