Thank you for the blog-link, Cynthia, and your thoughts. Here are mine...
Pace doesn't keep me turning pages. What keeps me turning pages is that I have any reason to continue reading at all, and that there's no impediment to doing so. I don't mind a slow novel any more than I mind a winding road. What I mind are third-class, unsealed roads and third-class, uncrafted text.
Prose can be hot, salty, bitter, sour, sweet, or savoury. It can be rich or delicate, thick or runny, but it cannot be clotted, turgid and lumpy like Aunt Beattie's porridge.
As for what keeps me reading, it could be anything. I might like the descriptions, the voice, a character, a conflict, a theme, a plotline, an arc... But what stops me reading is always the same:
Shitty prose.
