Gosh, far too many to list, but one of my loves was Rev. Awdry's series about the railway engines. I even had a crush on one of the engines, Gordon, I think . My father was a railway enthusiast so I expect the initial interest came from him...
All the books I read came from the local library as my family was in no position to buy many books (I've made up for that now, though)
I loved Little Grey Rabbit, too.
Wicked Little Letters? (funny film of a long-forgotten case)
