I too loved this book and the other in his series.
As a result of reading this book I created 33 characters from either fiction, film or history and used his technique to do the readings. I loved the process and whole learning experience (yep even after all these years we can still all learn.....lol)
To this end I have actually boxed in a separate box, my most enriched RWS cards which I use for such readings. I think the enthusiasm now for me is creating new characters every now and then to do another reading using his format. For those who want to try, it is interesting choosing a current TV soap character and doing the reading based on current story lines, and then comparing to who they progress.
I also keep a spread sheet of cards used and patterns seem to have developed with a heck of a lot of court cards showing up. (more so than in my regular readings where more cards are usually used in each spread)
The only other author who I feel has kept me enthralled with the simplicity of writing style/ humour etc has been Mark McElroy whose books I also enjoy.
Shame though we can't readily get hold of James' first book - I think I have more chance of juggling with soot or knitting with fog than getting hold of that!
