I just this afternoon finished reading The Nightingale. My friend Joan told me about it after her daughter Lori told her she must read it. Lori was right. I can recommend it highly. It's a novel that tells the story of 2 French sisters in WWII.
Every single time I read a book about the Nazi's in WWII and the Holocaust I am reminded of Isaac Feinsilver. I wrote about him once before after we visited the Dohany synagogue in Budapest in 2011. After meeting him, I asked my niece Beth (who has a masters in Holocaust Studies), to recommend some books I could read to better educate myself. She told me about these.
These are two, very powerful, true stories of women who survived the Holocaust. If you have read The Nightingale and loved it, I highly recommend you get them. I just took both off my bookshelves to begin re-reading.
