Even today, with such a huge amount of children's books available, modern children still become gripped by the Famous Five, Malory Towers etc. Better written books such as The William Books, The Chalet School etc don't seem to have nearly as much appeal to young readers.
Is it because she doesn't really ground her books in a particular time? I know some of the language and activities make it clear they're not set in the 21st century, but even though most of her books were written during the 40s and early 50s there's no mention of rationing, fathers having fought during the war or any very specific references to what was quiet a seismic period of British history.
Just curious to know what the on-going fascination with her books is for today's children?
