This book was engrossing because of its information regarding forgeries during WW II, but I was ultimately disappointed on two aspects of the book. First, as a Jewish reader, I was taken aback by some lack of knowledge concerning Jewish customs (ie, Jews don’t kneel for prayer and Hanukkah - the only Jewish holiday mentioned - is a minor holiday especially in Europe at that time period). Also, I was a bit taken aback that the informer—spoiler alert—-was Jewish, but not Jewish enough for the Nazis to arrest since he wasn’t 100 Jewish; the Nazis considered a person Jewish if one grandparent was a Jew.
My other disappointment concerned the plot. The odds of two 85 year old people being both physically and mentally healthy - and reuniting after so many years - is astronomical, but I’ll go along with the romance aspect. What was really missing was any mention of the children, whose real names were carefully recorded in the clever code, after the war. Was any effort made to track down these kids? Or to reunite them with family? Yes, I know the names were sent to Yad V’Shem in Jerusalem, but considering the novel’s title is The Book of Lost Names, surely more attention could have been paid to this aspect.
I was sorry I spent money on this novel.

I’m a retired English professor, love reading and my concentration and comprehension are high. But this novel was a challenge. The plot was interesting and there were long sections that absorbed me. However I found the language very difficult to penetrate, perhaps because it was a translation or the particular author’s style. I had to force myself to pick up the book although once I began reading, there were, as I mentioned above, engrossing parts.
So I’m not sure if I recommend this or not!
