One of the first pleasant surprises within this book is that it touches upon Deities and legends that go beyond the British Isles, which have up until recently held a bit of a monopoly on Celtic *anything*. There are myths and Deities from Germany, France, etc. My main complaint is that it is woefully incomplete. I would love to see more information about pretty much everything in the book. What I also found astounding was that Stewart could title a section "Mother Goddesses" (pg. 58) and only name ONE Goddess by name, and that one (of them all!) The Morrighan! Then delve more into Cernunnos as the Lord of All Animals and the Hunter God and Celtic Gods which I believe IS important on one hand - as the Goddess is balanced by the God; however that said, the God has his own section in this book, and when discussing the Mother Goddesses, I expected to read about Celtic Mother Goddesses, not about Cernunnos, "Mabon as The Divine Child of Light, the Celtic Apollo" as Stewart calls him, and quotes from The Mabinogion based on Lady Charlotte Guests's translation which is the most Victorian and repressed of the lot! Might give Patrick Ford's "The Mabinogi" a try if you're looking for something that will not edit the Welsh tales for Victorian sensibilities. I have a fair amount of respect for RJ Stewart and his work, however, what I found in this was a need for MORE balance and certainly MORE information - MORE research on the Goddesses in particular as he already has a solid base with the Celtic Gods. He knows his Gods, that's evident - but when it came to the Goddesses, there is where the balance faltered for me. Still, it's well worth a read, there is a LOT of great information in this book and it is a great start for anyone who is looking to get into actually studying the Celtic Pantheon in any way deeper than playing it lip service. I give it 3 out of 5 cauldrons.
