Enid Blyton (1897-1968) is a household name in Great Britain, but virtually unknown in the U.S. I discovered her when I lived in Singapore and Malaysia during my childhood. Many years later, on a return trip to Singapore, I combed the used book shops for her titles. The six books I found were read and re-read to my young sons. Our favorite was Mr Galliano's Circus, the story of a boy who finds that working in a circus isn't all fun and games. The Enid Blyton Adventure Series with the four children and their cheeky parrot, Kiki, was also a big hit.
Although not classified as literature, her books are a lot of good, clean fun. Apparently some titles contain stereotypes of that era (1930's to 1950's), but I am not familiar with those books. AbeBooks.com has a nice article on Blyton's contribution to children's adventure stories.
My knowledge of her books is limited to the few we own as a family. Anyone else know of her or have a favorite title?
