There are tons of great stories set during WWII. This is not one of them. It's not even much of a story, it just sort of meanders and then peters out. The main characters aren't much more than plot devices or symbols; in fact, the only people worth caring about are the mostly nameless refugees fleeing the Nazis, and the Londoners living through the Blitz. The sections of the book focusing on them are actually great. But if you want a book about a fascinating female character during the war, read Charlotte Grey. If you want a book about a small town affected by the war, read the Guernsey Literary Potato whatever book. If you want a book that focuses on the tragedy of the Holocaust, read Sarah's Key. If you want a book about nothing, read this one.
