I, for one, loved it.
If you are looking for a how-to on reading cards, this is not that book. Nor is it a history of Marseilles cards. So if that's what you want, I think this might disappoint.
That said, I really love it and it has already expanded my thinking on how the cards might play a role beyond my usual practice of reading. For me, it is a very useful, thoughtful meditation on the ways divination with cards can inform an entire magical life--the way they ask us to really look, and focus, and be curious, to ask the right questions. Card reading as a practice informs every chapter, and while some are more card focused than others, I believe there's at least one reading (with Zoya as in her previous) in every chapter, it's just that these readings ask questions ABOUT magic--if that makes sense. The last chapter or two touches on ritual beyond the cards.
I think a lot will depend on whether the reader is interested in how divination with cards expands and informs our lives beyond the reading table, if that makes sense at all. Because I am very interested in exactly that AND a fan of her work more generally, I'm a pretty biased reader, so take it with a grain of salt. But I've read all the how-tos and histories, largely thanks to advice from this forum, and this book is exactly the kind of thing I've been looking for. But again, not a manual or history of the Marseilles cards!
There is some overlap with the blog, but a lot less than I expected, and where overlap occurs, I found the essays to be clearer and more focused or sustained, as I'd expect from a book.
I'm not sure this helps at all, but I thought I'd offer my take on it. And I'll also say that I finished it yesterday and started back at the beginning this morning to give a closer read--that's usually a good sign for me that a book has value.
