Sarah's Key is a very sad tale, one I almost wanted to finish without the happy ending. This would have given the story a feeling of truth but the ending was just too good to be true. This however didn't ruin the enjoyment of this book, which shows how well de Rosnay can write a tale of historical fiction. I was in the mood for this type of book and couldn't put it down. The story kept me captivated UNTIL the end, where it fell apart for me. However, I would recommend this to anyone who loves a good book of historical fiction that keeps you wondering.
