I really liked this one! From Library Journal:
For 15-year-old Sharon Grossberg, June 6, 1944, is "Death Day"--the day she loses her mother to leukemia. Since her father is serving in Europe, Sharon leaves her Boston home to live with relatives in New York City. This novel is a chronicle of the last year of World War II in the lives of this large, extended Jewish family. The story focuses on Sharon as she struggles to cope with her mother's death, her constant anxiety about her father's safety, and her own coming of age. The cycle of life is presented in the birth of a new cousin, the marriage of another, the devastation caused by the death of friends and family members, and the realization of the horror of the Nazi concentration camps. The story is well crafted, and Goldreich ( Years of Dreams , Little, Brown, 1992) successfully evokes the mood, time, and place of the American home front during the world war. Recommended for most fiction collections.
