Sarah's Key

I'm currently reading the book Sarah's Key. It's about a jewish girl living with her family during the start of WW2. Her family is taken away and held in a arena with thousands of other french jewish families. The girl thinking that she is going to come back later that day hides her brother in their secret hiding cupboard so that he won't be found. She thinks that her father will come up and get him out, but that never happens. Alternating with present day, a journalist is doing a story on this event, but the French are not too proud of it and she finds it hard to find information. Meanwhile, her husband is fixing up his grandmother's apartment and through that and writing the story, the woman links herself to the young girl Sarah. I'm currently halfway through the book and I can't wait to figure out what's going to happen next and how they two characters are connected.
