this is the first book I've read about brigid and I feel like it was a good comprehensive beginning. I trust lunaea weatherstone as a tarot deck creator. I would say overall the life she leads is a little too religious for me - it seems like pretty much all her mundane household chores as well as her spiritual life involve an invocation etc. to brigid - it's a lot of mindfulness and singular devotion. so there was a lot in it that didn't appeal to me, but there were also a lot of pieces that were appealing.
the overall discussion of brigid as a goddess and as a saint, stories about her, her relationship to fire, forge, wells, sheep and cows, battle, etc. was a very helpful framework. weatherstone brings in other contributors who work with brigid to discuss their relationship to her, which is cool. weatherstone herself serves as a flamekeeper, so there is information about that. discussion of other goddesses related to brigid, both in celtic and other traditions. she refers extensively to carmina gadelica, a collection of folk prayers and incantations published in 1900 and there are other prayers. there are instructions for spells and rituals, recipes, instructions for crafts, meditations.
it read well and gave quite a comprehensive overview, and every once in a while there was a new to me or striking concept - like when you use a lighter, giving a thought back to your ancestors who put a lot of work into lighting and keeping fires. making and using lustral water. using a poetry oracle.
all in all, this basically hits on a ton of pagan, witchy, and devotional topics from sacred animals to the moon to candle magic and devotion, kitchen witchery, protection spells, divination, the significance of three, goddesses, tattoos, imramma, lorica, and other celtic concepts, etc. even taking what resonates with you and leaving the rest, it's a very rich resource.
