Earning Her Wings (USA 1981, Veronica Hart, Tiffany Clark)

I'll never know how hard it was for the little girl from the wrong side of the tracks to make it in the cutthroat world of modeling, but it must have been awful. Veronica Hart wrote the book on getting a foot in the door, but her protagonist, Carla, is forced to find her own way in a society that would rather she just go away. With the help of her friend Sally, who knows all the tricks, Carla proves that with perseverance, intelligence, and a little luck, anything is possible.
