Carolyn Cassady, who was married to Neal Cassady, the model for Kerouac’s Dean Moriarty, recently passed away. Her book, Off The Road, detailing her experiences with Kerouac and Ginsberg is now out in Kindle format. Excellent reading if the inside view of the “beat generation” interests you.
Interesting. I don’t know if this is in the same vein, but there’s also Ringolevio, by Emmett Grogan, which is a look at what happened in the 60’s from a low-key but influential player, though maybe of more questionable morals and veracity - he died of a heroin overdose, and some of his story is allegedly invented for dramatic effect.
