Editor for Teen Fiction Novel

Thanks for taking a look at the post! I’m looking for a human editor to help polish a teen fiction novel that was written by a teen author. Nothing in the novel has been created or edited with AI. We've worked with dozens of copy editors but never for fiction/novels so your experience is so valuable. The book is terribly romantic, aimed at young readers and needs a review for development, clarity, pacing, and overall readability with the ultimate goal of submitting for publishing. I’m looking for someone who can provide thoughtful feedback on the story, characters, and dialogue while preserving the author’s voice and style. Experience editing fiction for younger audiences is, of course, ideal. Any examples of your work would be wonderfully helpful.
