Thank you so much!!!
Thank you!!!!
Wow
With thanks for additions from Heron and Heather Awen.
With thanks for the additions of ‘After the Ice’ and ‘The White Goddess’ from Peter Jeffs.
Thank-you for this great collection of resources.
Hi, great site, but just thought I’d point out that The Men of the North is written by Tim Clarkson, not Clarke.
Oh, ta, sorted!
Thank you! I’ve just ordered one of the books on your list, “The Grey Mare On The Hill”. My patron Goddess is Epona and I’ve found it difficult to find anything about Her. (By the way, I am lucky enough to live in Wales.)
