I just got this and really think it's a great book. I am a UU and a pagan, so I was really looking forward to this book's release. The stories are short enough to share with a group of kids, and the suggested projects are simple to implement, yet get at the heart of the eight holidays in the pagan year. I expect to use this book both with my own children, and at the UU church I attend.
This is a quick read, the stories are written for children as well as adults, and the large type goes by fast. The "real life" stories give a nice dimension to the usual Pagan holiday lore that pre-teens might enjoy reading, while the info for adults give some great ideas on how to best celebrate the high day.
This book is what I'd call "Pagan stealth" written by a UU educator, it stresses the seasonal changes and connecting with the self and nature over specific Pagan theology or much mention of Gods. I question some of the historical information, but think that the ecumenical tone of the book will make it something that teachers and Pagans wanting to include non-Pagan friends will enjoy using.
My one big complaint is just layout style. I wish the book had had a few more illustrations, or that the big blocks of text had been broken up into columns or had headings that catch the eye more. Otherwise, it's a nice addition to the Pagan family's library.
