Now, this is highly fictionalized, but ... as is often the case with things in the occult world ... there are many kernals of truth unveild in the narrative. In fact, with some digging, one might even come up with some of the actual IRL protagonists. Anyway, this is a look at the 93 Current as manifested through Jack Parsons (etc.) ... I've only read about 1/4 of this myself, but what I've gotten through has held my interest, so I thought I'd pass it along ...

By the way ... there IS a handy menu for all of these, but it's not current, but can be found buried off at http://archive.org ... which is being difficult to contact today ... put the "Aparmenu" link from the bottom of any of those chapters into the search box there, and you should be able to navigate via that.
