A boy finds The Book of the Master in the cellar of his parents' house, and a new generation inherits the magical legacy. Anyone who has read Stejnar's The Book of the Master will also savour its sequel, which offers an even deeper initiation into the mysteries of the arcane world of spirits and the power of the human spirit.

Andy Mo is a young earth spirit who ventures into the human realm in search of his missing father, the gnome king Andimo. Baphomet, the Prince of Shadows, is holding him captive somewhere. He wants to prevent the old king from finding the document of the 'Formula of Nothingness' and revealing the last great secret to humankind: namely, how to free yourself from the power of evil once and for all.

Time is running short for Andy Mo to fulfil his mission, as earth spirits can no longer return to their spiritual home if they remain too long on the earth's surface. Fortunately, he manages to find some human friends of the same age who can see him because they believe in spirits. They help him search for his father. In return, he aids them with his magical abilities and gradually initiates them into the secrets of magic and mysticism.

Children, young people, and experienced esoterics alike can learn a lot from Andy Mo. He not only explains how magic works in practice, but also how you can 'magically' change your life in the most remarkable way without magic, simply through the power of thoughts. The secret of the 'Formula of Nothingness' is revealed for the first time.

Every thought can serve as a helpful spirit. But thoughts can also degenerate into demons. That's why it's important to control and master your thoughts. The power of your imagination is your magic wand.
