"Dear Writer: We loved this idea, and we found it very fresh and charming. We were eager to dive into your work! We liked the double narrative from [name of character] and [name of different character], and we think you really structured your story well.
....Unfortunately, we didn't feel like there was enough descriptive detail about [specific topic addressed in novel] past here – the glamour days of [place addressed in the novel] didn't really come alive for us on the page. Since this recreation of the past is crucial to the storyline, we felt that without it, we weren't as caught up in your characters and their lives as we wanted to be."
They love, love, love it.....but not enough. Note the hairpin turn at "unfortunately." Damn the past and its lack of details! Also, what's with the royal we? That's a whole lot of douchery.
