On a captivating level I would give this book about a 6. There are paragraphs upon paragraphs in some parts that really just explain the same point and become somewhat redundant. Painstakingly redundant. This is just my opinion.
However I will say this, as far as learning the basics and the sephiroth there is none better for a beginner. Even though it seemed I was reading a text book from college that also wasn’t designed to captivate, I learned A LOT ! Dion spares nothing in explaining the details. I highly recommend this book for anyone just starting out to study the mysteries of the hermetic Qabalah ! Yes it gets a bit stale but the knowledge your looking for is all there. These opinions belong to me only. It’s a must read but don’t expect fireworks !
