Liesl, Otto, and baby Mia's father has already been captured, and they get separated from their mother in a blizzard after only a few days on the run. Liesl had promised Mama that she'd keep her brother and sister safe, no matter what. They'll forage in the forests if they have to. Little do they know that there are hundreds of other parentless children doing the very same thing. And they far too quickly learn that, sometimes, to survive, you have to do bad things. Dangerous things. Wild things. Sometimes you must become a wolf.
