I admit that this just isn't the book for me, and that many others will connect to it better than I did. I found the black hole metaphor for depression boring and overdone, and I kept waiting for it to go in an interesting direction, though it never did. It is a critique of the way extreme capitalism - specifically the Silicon Valley tech industry - alienates, isolates, and uses and discards its workers, though it mostly read as the author hating the Bay Area and not really grappling with the gentrification being the cause for a lot of the pain and daily struggle. It also doesn't help that my last book before this was about an extremely mentally ill woman with magical physical manifestations of her mental illness who struggled to maintain her life at her corporate job and continue to have the funds to survive while her life unravels around her, and that one was really interesting, so I was mostly just disappointment by this.
