Fiction: Older couple, dysfunctional marriage: Taking out resentments on adult kids: Opportunity for self-reflection and growth.

Much like the title suggests, I'm after an easily accessible book that may have this dynamic in the main characters. Happy for the book to be either the perspective of the parents or the adult kids. OK if the book involves a parent passing away. Would be great if there's an element of growth, ownership and learnings from the parental figures. Thanks!
