This book is basically useless when it comes to explaining T.S. Eliot, but what isn't? It is also practically useless as a book of criticism on the Grail legends. However, it is a really great book on the occult. Much of her information about then-modern occult practice came from Yeats, which is hilarious, and her research into the topic is really great. Most other writers on the subject from her era are always saying things like, "If you know what I mean then you know what I mean," and otherwise being spooky and secretive. Not Weston. This book is therefore a good companion to the books of Arthur Edward Waite, et al, and way less irritatingly vague.
