Killing Miss Kitty and Other Sins — Marion Dane Bauer

The time is 1950. The place is a small town in the Midwest. The girl is Claire, and she has a new black friend. But in an all-white town, how open can the girls be about their friendship?
Now Claire faces being the “new girl” in school. A year later, she is confronting betrayal . . . and sin. Finally, she is fifteen and in love. But it is not a love that can be spoken of, least of all by Claire.
In five interrelated stories, Claire grows into a young woman, learning about racism, sex, and love along the way. Most of all, she learns about truth.
