If you count Zen and the Art of Motorcycle Maintenance, almost any fiction book with a philosophical angle would fit that description.

Or even books like “The Phoenix(/Unicorn) Project”.

perhaps they made the fiction/non-fiction Freudian slip? Here I was thinking "Are there any non-fiction (actually true) self help books?"

I thought it was pretty well paced as a novel until it got to John Galt's big speech which seemed childishly self-indulgent and then after that it goes to hell. The novel is about 1200 pages and it's pretty amazing that it held my attention for the first 800 because I've rarely been able to enjoy a novel for that long.

as a lite-BDSM wish fulfillment romance novel, it's quite compelling. better plotted and written than much successful romantasy today. the whole plot is about a bunch of hot rich guys fighting over who gets to dom the self-insert female protagonist.

there's another fantasy aspect, which is discovering your sense of alienation from family and society is really because you're part of a special but oppressed group and won't admit it to yourself, and once you embrace your identity you can find fulfillment, love, and community.

now, in this case, the repressed identity is "capitalist", which is a peculiar way of looking at the world. but if you ignore this, the emotional beats of the story (finding yourself, coming out, found family) also work for the LGBT experience, even perhaps neurodivergence. I think this is why so many confused teenagers find themselves very moved by the book and are later embarrassed to admit it.

on the whole, it's not high literature but competently executed, the only really stupid thing about it is Objectivism.

I think it appeals to people with toxic "lone wolf" mentality.

I think there are some good things in the 4-hour Work Week but the concept as a whole is problematic: e.g. Tim Ferris himself has more like a 400-hour work week. Rich Dad Poor Dad is a right wing scam. There is a psychotechnology that people call "magic" but The Secret and Think and Grow Rich won't teach you it.
