Carl Sargent book

Sullanciri2002

As I am just as interested in Sci-Fi & Fantasy books as I am in Tarot, I recently discovered that the co-author of a novel ... wherein one the main characters has "the Sight" and uses a version of the Thoth Tarot ... is also a psychology professor at Cambridge, and has written a book that bridges gaps between psychology and the tarot.
Has anyone read Carl Sargent's book on this topic, and if so ... is it a worthy addition the library of someone who already has dozens of books on the tarot ?
