There is no, one Holy Book in Wicca. There are several good, informative works on Wicca; including "Wicca: A Guide for the Solitary Practitioner" by Scott Cunningham, "The Spiral Dance" by Starhawk, "The Holy Book of Woman's Mysteries" by Z. Budapest or "The Witches' Bible: The Complete Witches' Handbook" by Janet and Stewart Farrar. The last one is NOT our "Bible", that's just the name and it is my favorite book about Wicca.
I recommend reading some of those, and other books about Wicca to get a good understanding of where our beliefs and morals come from.
