So begins the wrenching diary of Minnie Goetze, a fifteen-year-old girl longing for love and acceptance and struggling with her own precocious sexuality. Minnie hates school and she wants to be an artist, or maybe a speleologist, or a bartender. She sleeps with her mother's boyfriend, and yet is too shy to talk with boys at school. She forges her way through adolescence, unsupervised and unguided, defenseless, and yet fearless.

The story unfolds in the libertine atmosphere of the 1970s San Francisco, but the significance of Minnie's effort to understand herself and her world is universal. This is the story of an adolescent troubled by the discontinuity between what she thinks and feels and what she observes in those around her. The Diary of a Teenage Girl offers a searing comment on adult society as seen though the eyes of a young woman on the verge of joining it.

In this unusual novel, artist and writer Phoebe Gloeckner presents a pivotal year in a girl's life, recounted in diary pages and illustrations, with full narrative sequences in comics form.
