From the back of the book:
Inscription of Power
The written word is power, for through the word comes the name, and through the name comes mastery. If the written word is power, this tome is power incarnate, for here the names of magic are inscribed. In this tome the glorious Order of Hermes shares its profound wisdom, awesome magical creation and devastating spells, infusing their might into the page for all to read. Here is written the word of magic. Here is power for the taking.
