This is an excellent, wonderful book about a girl refugee from Nazi Germany who has come to live with relatives she doesn't know after losing her immediate family. Her teenage cousin welcomes her and grows impatient at the girl's inability to forget the past and embrace her new life. ( )

Not my own review but it says everything:
Born in 1928, Rhoda Kaellis gathered the experiences of 15 Holocaust survivors for the fictional story of 12-year-old Sarah Carozo, the only child of a Jewish family in post-World War II New York City, and Lilly, her Belgian cousin who comes to live with her after her parents have died in a concentration in The Last Enemy (Arsenal Pulp, 1989). The book arose after Rabbi Victor Reinstein of the congregation Temple Emanu-El in Victoria suggested recording recollections of the Holocaust in 1987. Kaellis located 15 surivivors and recorded their histories over a period of nine months. Kaellis and her husband Eugene Kaellis co-wrote a seniors' advice column called Primetime and co-authored Satisfy: A Relationship Manual.
Rhoda Kaellis' The Last Enemy, a very moving story about Lilly, a pre-teen Jewish girl, who comes to New York to live with relatives following World War II. Lilly's parents had been killed in a concentration camp and Lilly had been "hidden" in a Catholic orphanage. As the years pass, Lilly experiences enormous emotional struggles as her Catholic upbringing conflicts with her new Jewish "home." Lilly, seeking permanent relief from her problems, commits suicide by sticking her head in a gas oven.
