The plot of the 'Everything is Fine' novel could potentially revolve around a utopian or dystopian world where people are made to believe that everything is fine through some form of control or manipulation. Or perhaps it's about an individual's journey of self - discovery where they initially think everything is fine in their life until they start to uncover deeper issues like family secrets, unfulfilled dreams, or relationship problems. It could also be a story about a community that tries to maintain an appearance of 'everything is fine' to the outside world while internally there are power struggles, social inequalities, or other forms of unrest.

I don't have information about the main characters in this graphic novel. It could be a group of friends, or a family perhaps. Without reading it, it's difficult to tell.
