A bit of a confusing book, but is an intersting read. The book itself contains a number of Fey Lords and their respective domains outside the structure of the Seelie Couts. Some of them like Queen Mab is a familiar staple for Celtic Lore, and others pull from other cultural legends.
The book is ambitious as it tries to redfine the fey, by expanding and classifying various fey lineages in its bestiary section. I get what it was trying to do with the subtypes, but it made it most confusing. Hopefully additional books will bring a bit more clarity, looking at all the fae and classifying them in their proper Kith without the need of subtypes. The book got me excited and made me revisit White Wolf's Changeling.
Looking forward to the other books they have planned.
