Prospero, I agree with Miss Kenton but I found Mr Stevens to be about the most exasperating male I've ever come across in literature. He was so unemotional and reined in, that I wanted to give him a good kick in the shin.
I loved Atticus too, Kylie, but also the three children Scout, Jem and Dill ( Dill I believe was based on Truman Capote)
I think my favourite Harry Potter character was Hagrad.
Just thought of another one - Anna from 'Mr God This Is Anna' by Fynn
