Feodora and her mother live in the snow-bound woods of Russia, where their closest neighbours are wolves. Feodora's mother is a wolf-wilder, and Feo is a wolf-wilder in training. Like the wolves, Feo has learnt to be wary of humans - even before the soldiers arrive with their guns and threats. And when the soldiers do their worst, she goes on the run with just a fugitive boy and her wolves for company - to rescue her mother and save her pack.
