This wonderful book has such a wealth of information on the Moon, her passage through the skies (and constellations) and how this effects us on Earth. It goes into great detail when describing each moon sign (not as a personality profile) and how it affects our bodies, eating habits, weight, health, the weather, decisions, healing. Such important knowledge, yet we've let it almost disappear.
When I first got this book I flicked through and found a passage that stated filing or cutting your nails on a friday night after sunset makes them grow healthy and strong. Having never had a fingernail last longer than an hour, I immediately decided to try this out. And it works! Even the authors say they can't explain it, but my nails are so strong and durable and white. People think they're false. It convinced me this book had secrets of our universe that I could learn about, but probably never fully comprehend. I knew it could teach me some real truths (more important than fingernails).
It also includes times for collecting and growing herbs and when to do certain household jobs like fix the roof. I know for certain other Moon books have used this as a source for their information. Forget the rest and just invest in this great volume. It teaches so much about the magic of Nature, in a very down-to-Earth and reverent way.
It also has extensive information on bio-rhythms and how to calculate your own. It takes a bit of maths, but the self-knowledge you gain is truly indispensable. I now understand my own energy peaks and troughs and don't over-exert myself at particular times of the month.
I would say it is an absolute must for any Pagans, but also for anyone else who just wishes to be more in harmony with the world around them. It is so important we are in rhythm with Nature. We have so many artificial time-keepers and influences, lets remember and harmonize with the most original and ancient- our Moon.
