What a strange novel...
There's no drama or tension. In an account from a survivor of three years in a concentration camp... It could almost have been a soap opera. Lale and the Friendly Nazis Who Help Him Find Love."If you are savvy enough, Auschwitz is a piece of cake!"
He gets caught by the Nazi's with a mattress of jewels and money, comes back from getting a severe beating after his girlfriends' friend gets her SS boyfriend/rapist to free him, then goes straight back to what he was doing. And pays off the guard for the female block so he can have private dates with his girlfriend in her bunk.
He gets caught by the Russians after escaping, and gains their trust so quickly that he simply walks away when he's had enough of being a pimp and wants to find his girlfriend. (By the way, the girls he procured for their parties every night had a great time. The Russians were known for being considerate lovers around that time, ignore anything else you might have read.)
It's just so light hearted and lovely... And I'm no historian but some of the events described seem very unlikely to have happened. But apparently it's going to be a film.
I'd put this one next to The Help in the genre "Yay, it wasn't so bad after all! (We didn't think it could have been...)"
