WWII 

My name is Lucie Blaise. I am sixteen years old. I have many aliases, but I am none of the girls you see. What I am is the newest recruit of Covert Ops. And we are here to take down Hitler. After the Nazis killed my brother on the North African front, I volunteered at the Office of Strategic Services in Washington to do my part for the war effort. Only instead of a desk job at the OSS, I was tapped to join the Clandestine Operations--a secret espionage and sabotage organization of girls. Six months ago, I was deployed to German-occupied France to gather intelligence and eliminate Nazi targets. My current mission: Track down and interrogate a Nazi traitor about a weapon that threatens to wipe out all of Western Europe. Then find and dismantle the weapon before Hitler detonates it. But the deeper I investigate, the more danger I'm in. Because the fate of the free world hangs in the balance, and trusting the wrong person could cause millions of lives to be lost. Including my own. - from Amzon
