Novels about marriage and family life used to fall into the slightly insulting category of "domestic fiction." Judging by some of the novels written today, what might once have been considered domestic is now in no way domesticated. Events that take place within the home and, specifically, within a marriage can be some combination of surprising, disturbing, sexy, moving or funny.
