It's supposed to be a letter from a young woman to her mother. But it seems more like a memoir or a diary to me. And I know I wouldn't tell my mother stuff like that. So yeah- there's a lot about her relationships with her lovers. And she mixes in recollections of her childhood.
It's an easy, fast-paced read. She presents the story as a series of dots, instead of one constant line. But what seems important or relevant to her aren't necessarily major events, but events that made her feel or think.
