Four stars are for the concepts the book presents, not because it is particularly well written. It is interesting and develops some incredible relationships. In particular, matrices can be constructed using celestial periods which yield musical harmonics, and that the stability of our solar system is based on an intricate system of energies from all the other planets and our moon.
But... Although I've got a degree in math, I'm not real familiar with astronomy. In some chapters, I had to stop several times, get online, find out the point this author was trying to make, then go back to this book once I figured it out. It was a lot of work, and it didn't need to be this difficult to present.
Here's a prime example from page 38: "As seen in the last chapter, the practical year is divided into five equal pieces by the eightfold, Fibonacci-based synodic year of Venus."
This could have easily read, "Five Venus orbits equal eight Earth orbits, and this 8:5 ratio approximates the Golden Mean." Whew! It may not sound as intellectual, but you don't have to re-read it five times to get the meaning.
On a positive aspect, the figures (drawings) showing relationships between orbital periods, days, etc. were excellent and a great aid in visualizing the relationships.
Even with the difficulties, it is well worth reading.
