Feodora and her mother live in the snowbound woods of Russia, in a house full of food and fireplaces. Ten minutes away, in a ruined chapel, lives a pack of wolves. Feodora's mother is a wolf wilder, and Feo is a wolf wilder in training. A wolf wilder is the opposite of an animal tamer: it is a person who teaches tamed animals to fend for themselves, and to fight and to run, and to be wary of humans.
