This was very difficult for me to get through- a friend who is studying to be a druid rec'ed it to me. It was hard to get through because I am familiar with Irish mythology and folk religion, and have spent time digging into mythology and the early celtic church. While this has an anglo-saxon focus and was focused on recreated traditions, it was so rife with historically inaccuracy it was so hard for me to read. I appreciate that people of European descent should engage with their past, traditions, and connection to the Earth, without appropriating closed cultures. I can get behind all humans seeking to connect with the Earth that we cannot disentangle ourselves from, and looking to our family histories. But I wish this book was more open and clear that they are created a modern practice- while helpful to some people in connecting with the land and their inner work- and that it is not based in history, but inspired by. It is also frustrating to me that the English men who founded "modern druidry" are the same who looked down upon the Irish language (and Gaelic and Welsh)- and did not seek to look those existing and living folk traditions due to ethnic prejudice. 

I'm going to refrain from giving this a star rating.  I read this book as part of the curriculum for the AODA, and it's interesting as a part of the Druidry revival's history.  Nichols founded OBOD, a significant contemporary order, and he has lots of interesting things to say about various Druid leaders that came before him; as a text that is part of Druidry's history it's an interesting read but it is not a good source about history.  There are definite issues with accuracy, and lots of totally unfounded speculation; while some footnotes are present, many ideas are simply stated with no references.  I think the contemporary audience who will be interested in this book is very, very limited.
