I have been delaying writing this review because I felt a pressure to really capture the essence of it, to say something which was neither jerking myself off for having such uncommonly good taste in (extremely, almost obnoxiously well known) sad girl writers, nor uselessly retelling the major beats of the story as if you can't read the fucking plot section of the wikipedia page yourself.
The plot is really beside the point. Play It As It Lays is a mood piece, capturing the inner experience of being a thin, attractive, materially comfortable LA/hollywood woman whose personal relationships are shambolic and whose attitude towards life is one of increasing incuriosity and numbness. For obvious reasons, the backdrop of LA, california, vegas, and the nevada desert are a perfect fit and really ring true. One begins to feel sorry for the wealthy californians and the hollywood B-tier, truly sorry: not for the vapidity and materialism which are presented fairly sympathetically, but for the loneliness, coldness, and dissociation, the impossibility of enduring meaning or even trust.

The only Didion I've read is Run River (which I liked quite a lot), but I've been meaning to check out another. Really dig the cover shown here, actually, is that the one on your edition? Read Hrabal's most famous one, Closely Observed Trains, last year after watching the film. Both are amazing.
Hey everybody, get a load of this tryhard f*g watching an old black and white movie with subtitles then reading the czech novel it was based on! But really, it is one of the greatest comedies, both the book and the film. I strongly recommend Too Loud a Solitude, which (after several drinks), I could almost describe as the joyful autistic alcoholic communist-dissident male response to the portrayal of feminine proto-neoliberal nihilistic ennui in Play It As It Lays. This is the cover you get when you order it new off amazon in the US. I can confirm that if you leave it tastefully askew on your coffee table, the hoes will be drawn to it, flip through it briefly, and declare that they "love Joan Didion" after seeing a documentary on Netflix about her and have been "meaning to start reading fiction again." Do not loan it to them, but instead offer to take a picture of them pretending to read it, for instagram.
It gives me joy that such covers are still being attached to books in America, and I appreciate the word of caution re: requests to borrow by hoes.
