Because It Is Bitter, and Because It Is My Heart by Joyce Carol Oates
Iris is the only witness to the crime.
The two of them are growing up in the early 1950s in a New York industrial town where racial boundaries keep people apart—or bring them together in explosive scenes of fear or desire. The secret link between Iris and Jinx is not only their attraction to each other, but a murder and a bond of passion and guilt is formed between them. How this one irrevocable, tragic act shapes their lives and alters their destinies becomes Joyce Carol Oates’ finest, emotion-packed novel—a work the critics are calling a masterpiece, the best work of America’s best writer of contemporary realism.
