Well, first of all, if 'ehrengard novel' is a work that delves deep into human emotions, it can be a valuable addition to the literary world. It could have a way of presenting moral or ethical dilemmas in a new light. It might also be important for the language it uses, whether it's a very descriptive or evocative language. And if it has a plot that is both engaging and thought - provoking, it can attract readers who are looking for something different from the mainstream literature. It could also be a source of inspiration for other writers in terms of its narrative structure or the way it handles certain topics.
I'm not entirely sure as it might be a relatively unknown or niche novel. It could hold significance in terms of exploring certain themes like relationships, society or personal growth specific to the story it tells.
