I am a fan of historical fiction. All time periods, although I find that if it's a time period I know "too much" about, I have a hard time enjoying the book because of the inaccuracies.
However, I greatly enjoyed Sarah's Key, written by Tatiana de Rosnay. It was two stories in one- the story of 10 year old Sarah, a Jew living in 1942 Paris, and the story of an American journalist named Julia, who is determined to bring Sarah's story back to life.
I don't normally enjoy books written in this format. I find it distracting, for both the reader and the author. But this book was superbly done. There are so many things I want to say about this book, but I won't for risk of spoiling the ending.
