A Self-Interested Female Lead: Noble, Glamorous, and from a Powerful Family

Looking for books similar to *The Black Moonlight Is Full of Lies (She Is the Black Moonlight)*. The female lead is clear-headed and calm, and she's a self-interested person. The story is substantial and exciting, and very well-written. Every character is distinctive, and it doesn't vilify the original female lead. The characters don't act stupidly, either.
