I really really liked this book (I find the WWII period surprisingly a very good setting for romance. It was done very well, though the beginning is slow. I like the historical aspect of it as well. Anja the Liar's main character Anja is a conflicted main character who is at odds with her own identity in a place where the only thing you have to prove your name is a piece of paper.
The WWII era is fascinating to me because it's when the world went crazy. Beforehand, people paid attention to frivolous things like class and status, and even materialistic wealth. But during WWII, suddenly everything changed and absolutely nothing mattered except for staying with your family and getting away with your life.
