Play It As It Lays by Joan Didion

The novel centers around a woman named Maria Wyeth, a former model and actress, who is drifting through life in the 1960s Hollywood scene. As she struggles with a failing marriage, a difficult relationship with her daughter, and a career that's spiraling downwards, she grapples with existential despair. Told in a series of fragmented narratives, the story reveals Maria's mental breakdown, her self-destructive behavior, and her desperate attempts to find meaning in a seemingly meaningless world.
