A great hook delivers:
I Just Made This Up by J.D. Jacobs
10 feet under and never felt better.
In this hook we are instantly hit with questions. Who is she? What is she doing ten feet under and why does she like it so much?
So what's the problem?
Nothing if your book is about a delirious dead girl. If not, I would strongly urge you to reconsider using this line, unless you welcome the prospect of a deluge of hate messages by a bunch of angry readers who feel duped.
Your first line is meant to be a reflection of what is to come. A taste of the rest of your work.
If the hook has nothing or little to do with the central theme of your novel it is unfair to your readers who have been led to expect one thing and instead been given another.
The hook is a promise of things to come. And like all promises, it needs to be delivered.
