The Wolf Wilder by Katherine Rundell - Middle Grade
Feodora lives in the snowy Russian woods with her mother and they are Wolf Wilders. They untame domesticated wolves that are no longer useful to the rich that had them tamed in the first place. They teach them how to run, sleep outside and how to relearn their wolf instincts so that they can survive in the wild again. This is how Feo has been brought up, around wolves, but the evil General Rakov has threatened to shoot any wolves and take her mother away if they continue wilding. With the help of an unlikely friend and her wolfpack, Feo must find a way stop Rakov and his men.
