Of the Llewellyn's Sabbat Essentials books that I've read so far, I liked the Ostara book the best. I love that the book isn't entirely wiccan and that the author addressed the whole Eostre problem from a historical stand point rather than stating it as fact. I also loved that she explained a lot of the correspondences, especially the deities, and why they correspond with the sabbat rather than just listing them and asking the reader to just take their word.

I will say, however, this book (like the rest in this series) is geared towards beginners, so there won't be a lot of new information for more advanced practitioners, except maybe some new ideas for meals or meditations. With this in mind, I really do wish the series would include some more subtle rituals that learning pagans could do if either they're living situation doesn't permit elaborate rituals/spell work or they just want to ease into it.

Beginner and discreet/subtle rituals/spell work is something that I have long felt is really missing in the pagan literature that is available, and a series geared towards beginners should be a perfect place for it. I just think it's a missed opportunity.
