This is both an adoption story and a Holocaust story. The author survived not only the Holocaust but multiple experiences of being brutally torn from people whom she loved and trusted.
When she was only about four, her parents and older brother were murdered in the Holocaust. She had been living with a Ukrainian Christian woman. The Ukrainian put her out on the street and abandoned her to certain death after she realized Sara's parents would not be paying for her upkeep anymore. Sara eventually landed in a Christian orphanage, using another name and hiding her Jewishness. She was very sick, perhaps dying, and after she left the orphanage had to spend about a year recuperating from all the illnesses and injuries she'd accumulated from her life on the run. She was adopted by a childless Polish couple, the Pilches, who raised her as their own, and took it in stride when she told them she was Jewish.
After the war, Sara's surviving uncles and grandfather found out where she was and demanded that her adopted parents return her. Sara, however, wanted nothing to do with them, and the Pilches didn't want to give her up. What followed was very traumatic for Sara, as she found herself moving from her adopted parents to her biological relatives and back again, as well as brief stints in an orphanage and a boarding school while both sides battled over her fate in court. The court ruled in favor of her biological family, who took her out of Poland as soon as they could. She never saw the Pilches again.
Sara adapted well to life in Israel and still lives there today. She never went back to Poland. She writes lovingly of the Pilches (although without making them into saints), but doesn't have anything kind to say about her uncles and grandfather. I don't know whether she was just trying to show a child's perspective, or whether, as an adult, she still feels anger and resentment towards them. I'm not sure how much contact she had with them after she arrived in Israel; it seems that rather than move into the family home she lived in a kibbutz.
Both sides were trying to do what they thought was right, but their positions were so radically different. After she was basically imprisoned in her grandfather's apartment (she kept trying to run away so they kept her locked up), she asked to write to her parents, meaning the Pilches. Her grandfather angrily responded that they weren't her parents, they were gentiles, and it would be better for her to die as a Jew than to live as a Christian. Even into adulthood Sara carried a great deal of guilt.
I liked the parts of the book that were about her childhood and the custody battle, but I thought the parts where she wrote about her adult life were both uninteresting and unnecessary. The narrative skipped around a lot chronologically, so sometimes I wasn't sure about the order of things. I think it could have used another pass at the editing table. But the story is compelling and I think both adoptees/adopters and people interested in the Holocaust would benefit from reading it.
