There are two Jack Parson bios; this and "Strange Angel" (the second book was the source for the short-lived TV series). Growing up in Los Angeles I was aware of the stories connecting JPL, L Ron Hubbard, Sci Fi fandom and the the OTO. I was eager to dig into this mysterious noir Los Angeles.I picked this bio over "Strange Angel" since it is published by Feral House (an LA based publisher of esoteric topics) a year prior to "Strange Angel". I did enjoy the history of rocketry, and the ambiance of pulp era Los Angeles. What I did not enjoy was the extensive details of "magikal workings", "enochian alphabets", etc. - that stuff is boring to me. The author, John Carter, appears sympathetic to the idea (along with Jack Parsons) that this hokum could manifest in the material world (note- it was windy in my neighborhood yesterday, and I have never tried summoning an Air elemental).Another boring bit was the intro by R.A. Wilson. I imagine in the 1960s Wilson was bit of an edgelord, but his contemporary criticism of 'the man' is what I hear from all the establishment hippies.There is a nice Amazon review of this book by Gene Rhea Tucker, he was patient enough to read both bios and contrast them. I think the intended audience of this book was Crowleyites (no doubt why they included the word 'Occult' in the sub-title). If that's not your thing, read the synopsis of "Strange Angel"; it may be a better fit.
