I’ve critiqued two novels recently where the hook was so deeply buried that I spent the first 8-10k words wondering why I was reading the story.
Don’t do this.
Whatever your story hook is, put it up front. Be open about it. Let your reader know that THIS is why they are reading.
Otherwise you are in danger of losing them.
If your reader is saying “so what?” then take a look at your hook. Where is it, how strong is it, how clear is it. And if it’s not right there, at least in the first chapter, then put it there.
It does not pay to be vague and mysterious in your opening chapters.
