What a good question! I've given away so many books that I'll have to try to remember some good ones that are no longer with me ...

The Craft by Dorothy Morrison. Workbook with great visualization exercises.

Apprentice to Power by Timothy Roderick. A male Wiccan viewpoint! Memoir plus interesting explorations of Eastern religions and psychology.

The Complete Idiot's Guide to Wicca & Witchcraft by Denise Zimmerman. Comprehensive!

The Heart of Wicca by Ellen Cannon Reed. Controversial and well-written. Author levels valid criticisms of much that is superficial and sentimental about popular Wiccan culture.

The Circle Within by Dianne Sylvan. Interesting focus on day-to-day Wiccan spirituality.

Plus, I'm trying to develop a "Pagan-Themed Mystery" subgenre over on the Mystery Books site, and I've so far posted reviews of Rosemary Edghill's Bast trilogy. So I could recommend those if you're into mysteries.

Actually I could ask for help as well. The only other pagan-themed mystery that I've run across is M.R. Sellars's Rowan Gant series and I found the first book short on writing talent, and heavy on the violence so I've been reluctant to add it. But if anyone has heard of any other good pagan-themed mysteries, please list them here and I'll check back!

This may be a long shot, though! It seems that pagan-themed fiction tends to run towards the fantasy genre and not the mystery genre. I mean, when was the last time we ever saw a Wiccan police procedural?
