The book isn't a fictional story, but it tells the "biography" of a magical tool. Tyson argues that while modern culture sees mirrors as simple objects for checking our hair, they have a long, mystical history as doorways to other places. He breaks the experience down into three main parts:
He gives step-by-step instructions on making a specific nine-sided black mirror . He emphasizes that the process of making it—the heart and dedication you put into the carpentry—is what actually "gives it life".
He explores how mirrors have been used across different traditions for divination and connecting with other dimensions.
Tyson describes the mirror as a "psychic window" that can be used both to see things (scrying) and to send energy or messages out.
He makes it clear this isn't a "craft project" or a toy; he treats the mirror as a "working occult instrument of immense potency". How to Make and Use a Magic Mirror:... book by Donald Tyson
