The book memoirs of a childhood bookworm prompted me to think, what I used to read.
I can remember The worst witch was a popular book at school aged 7. I think people gave it to each other as birthday presents. I can remember it had pale purple cover, with picture of witch. I can not remember the story apart from think it was about young witch not been very good etc at spells rather than being the worst as in evil. Lots people reading at school.
