When I was a child (80s) read loads of Enid Blyton books (passed down from siblings, library etc) and in the past few months have read loads of these free online (original/early editions, none with updated texts) - prob way more than when I was a child!
Although dated in many ways I have a fondness for the "family" type EB books - (house on the corner, family at red-roofs, six bad boys) which were less well known than Famous five/secret seven etc.
Also I have read several books about EB (biography, book by her agent and a book by her daughter about her childhood) and found these really interesting, of course like all authors/famous people in general who you think you know their lives are more complex (and interesting!) and different to how one would expect and how they are "presented"
