From Terry's list on Celts and Druids.
My copy of this book is highlighted and dogeared to the max. When searching the word Druids, you usually come up with books on magic or books related to the neopagan movement which calls itself "druidism". This book, however, is a summary of what we really know about them and is based on solid research. Scholarly yet highly entertaining. Awesome book!
