If you have researched books on the Corpus Hermeticum, you know that most of them are written for scholars, with much emphasis put on literal accuracy of translation, even to the point of rendering them sterile of any fathomable esoteric concepts.
Then, there are other books, just a few, that deviate too far from the literal translation in an attempt to shoehorn in the particular author's personal beliefs.
This book fits neither category. It is not perfect, none of the books we have on the Corpus Hemeticum come anywhere near perfection. But, at least, this book is quite readable and does avoid creative re-interpretation by the authors.
