My stories tend to bring people from isolation into community - with at least one other person, usually with a whole community of people - so that they find themselves accepted back by a world that they kind of fled from.
My books do have a sort of romantic community at the end - people coming together. But on a more basic level, I always see them as being about power, in the same way that Harry Potter books are pitched to a population of young people who really have no power.
You could go church and you could describe your worst behavior, your worst self, and despite your worst behavior you would be forgiven and then redeemed and then accepted back into the community through communion. So you didn't have to carry this burden your entire life. Once a week you went someplace you went someplace where you could really look terrible and be loved despite how terrible you were.
