kindness

A few months ago i read i read a book (i cant remember the title) about a girl that almost everybody avoided and called weird because shelokked different from her sisters and she had a special ability. One day she got a letter from a boy, that she later found out lived in the forest, which caused im to aprreciate things that others wouldn't. The two continued to send letters to each other and became friends because they focused on each others personality instead of being influanced by what others said about them. One day the boy find out that his new friend is in trouble so he leaves the forest and traveles to her village. Once there he does all he can to help her save her father. Which shows all of the people that once picked on her that everyone and everything diserves to be treated fairly and being different isn't necessarily a bad thing.
