My favourites were the same as just about everyone else’s on here, with some notable exceptions. I didn’t like Enid Blyton, except for her early nature books. I found her writing dull and the children she wrote about very boring. Same goes for the children in Arthur Ransome, so I left those to my brother. i didn’t like the characters in Little Women, either.
The children in Noel Streatfeild’s books, or Anne of Green Gables, Katy, Just William and so on were the interesting ones to me. Loved anything ballet or theatre-related. Ponies, too, within reason, but oddly enough I’ve never read Black Beauty. Lorna Hill managed to combine ballet and ponies, which was ideal.
I am struck by the fact that some of books posters have mentioned weren’t even published until I was more or less grown up! You must be so much younger than me. That said, it applies to the Drina books by Jean Estoril (more ballet) and I’ve read all of those. I don’t care if I was grown up when I read them!
