The mother of all moon books shines anew. The success of our actions largely depends on the right timing of our endeavors. Careful observation of nature and the moon phases guided our ancestors.

Now, 25 years after the first publication of the classic moon book, there is a special anniversary edition in a revised and expanded version.
