Oh I love this thread - my favourite fantasy author. Just how may world's did she build? Libraries in my area are reporting an upsurge in parents getting out her books for their children.
I loved the lot as a kid - Amelia Jane, Faraway Tree, Adventure Series, Mallory Towers, Adventurous (sp??) Four, St Clares, Secret Seven, Famous Five, Mystery Series, The Barney Mysteries (my complete favourite), Misteltoe Farm, Young Adventurers, Mr Twiddle, Mr Muddle - oh a whole host I give up lol I set myself a goal to read all of her books I managed about three-quarters. I also used to get an Enid Blyton Annual type thing with short stories in it which I still have a couple of. (umm I still reread them).
