A Thought-Provoking Book

I am at the cottage this week and have devoured a couple of books. One really took my breath away. Called "Sarah's Key", it's about the round-up of Jews in Paris on July 16, 1942, by the French police, under orders by the Nazis. The story is of 10 year old Sarah, who is one of the 13,000 Jews rounded up and sent off to camps near Paris (one of these camps has since been turned into affordable housing---can you imagine living there, knowing its history?). Most never returned. Sarah, confident she will return home shortly, locks her younger brother in their secret hiding compartment in their apartment. I won't say what happens in case you want to read the book.
What I will say is that the book alternated between hearing Sarah's voice, and a journalist's voice, who was researching the event 60 years later. I have to admit, I was disappointed when we stopped hearing Sarah's voice. I desperately wanted to hear more of her life and experiences, from her own mouth.
I am also ashamed to admit that I had never heard of this round-up before. Called La Grande Rafle at Vel'd'Hiv, these Jews were all herded into a velodrome used for cycling races, where they lived for days in unmentionable surroundings.
Why did we not learn of this in school? Was it because the French did not admit their complicity in this horrendous event until decades later? Was the Canadian government afraid of offending the French by teaching this history? I realize many countries committed atrocities during WWII. We all learned about the Holocaust---where are the history books on this?
