Because the novel “allows for no proper mourning or working through,” you write, there’s a danger that “it can serve as a prelude to, or be used as an excuse for, wholesale, reactionary and even totalitarian movements of redress and moral restoration.”
Of course, "movements of redress and moral restoration" need hardly be reactionary or totalitarian. I am not sure Versluys grasps this. Perhaps a good 9/11 novel would focus on the justifiable rage for redress and not bend over backward to understand things from the bad guys' viewpoint. Some of us are not inclined either to forgive what happened on 9/11 it or to forget it.
