I received this book for free through LibraryThing's Early Reviewers.
This was a cute, light read. I really liked reading the letters from Lulu and learning about how she was dealing with the war. I've always been interested in World War II and how it affected Americans. I also loved the secret room. I've always wanted to find one.
I thought Billie's relationship with Mitch went a little too fast. I also didn't like him that much. I liked him when he was Mr. Complainer, but after that he got a bit annoying.
