This is a short book, barely over 100 pages, and they put extra spaces between paragraphs so it would be that long. Nevertheless, it is an important study of the nature of the relationship of what we call magic and religion in the Old Testament.
Some of the interesting findings are that the way different authors (documentary hypothesis authors, that is--J,E,P,D) see the issue of magic. She finds that both religion and magic are rooted in the same conceptual relationship between man an the world and that separations between the two ideas happened incrementally and diachronically. This is an important discussion of the issue and justifies whatever they needed to do to make this long enough to become a book.
