November Books 11) The Demon Headmaster, by Gillian Cross

Gillian Cross was a new writer for me; I enjoyed this children's story of sinister headmaster with supernatural powers planning to Take Over The World, a blended family, commentary on children's TV game shows, and knowing winks to Nineteen Eighty-four. Will look out for the sequels if F enjoys it too. Thanks to chess and redfiona99 for recommending it.
