The wolves of Willoughby Chase

This novel is the first in the Wolves Chronicles (aka The Wolves of Willoughby Chase Series), a series of children's novels set during the fictional early-19th century reign of King James the third.

A large number of wolves have migrated from the bitter cold of Europe and Russia into Britain via a new "channel tunnel", and terrorize the inhabitants of rural areas. Read about the adventures of cousins Bonnie and Sylvia and their friend Simon the goose-boy as they thwart the evil schemes of their governess Miss Slighcarp, and their so called "teacher" at boarding school, Mrs. Brisket.

The story was made into a film in 1989.
