The Wolves of Willoughby Chase by Joan Aiken

Can you go a little faster? Can you run?

Long ago, at a time in history that never happened, England was overrun with wolves. But as Bonnie and her cousin Sylvia discover, real danger often lies closer to home. Their new governess, Miss Slighcarp, doesn't seem at all nice. She shuts Bonnie in a cupboard, fires the faithful servants and sends the cousins far away from Willoughby Chase to a place they will never be found. Can Bonnie and Sylvia outwit the wicked Miss Slighcarp and her network of criminals, forgers and snitches?
