The Yellow Bird Sings

I'm not sure how I found this book. But I may have been looking for books written about Poland. I am 99% Polish, and all four of my grandparents were born there.
I loved this story. I find stories about WWII to be very interesting. This is a story of a Jewish mother and her daughter who hide out in a neighbors barn to keep from being found by the Nazi soldiers. But their hiding place becomes less secure and they must move on. The neighbor lady suggests the daughter be sent to a catholic orphanage to stay safe. The mother leaves the barn, and with only an address in her pocket journeys though the forests at dark to try to find her daughter again.
Note: I loved the author comment at the end of the audiobook.
