Where the preceding book, A Wicked Pack of Cards, enthralled me in spite of its enormous detail, this volume lost me. I started to lose interest during all the detailed accounts of the Golden Dawn, its beliefs and infighting, and I ended up skimming through succeeding accounts of the plethora of mystery schools, societies, and various crackpots and scammers that line the history of 20th century esotericism.
It was only during the biography of the influential Eden Gray that I momentarily got some interest back, but that seemed too little too late.
I think the authors are burdened with too much history, and a desire to be complete. Problem is, catalogues are not fun to read. It is a shame that they abandoned writing about tarotism post 1970, and did not break up or whittle down the scope of study. There is much in here of interest, but I feel the narrative ultimately spirals out of control.
