Dear Miss Snark:
I have re-read your posts on the difference between a synopsis and a hook, but it seems to me at least a small portion of the hook would need to contain some synopsis-type verbiage.
One More Night to Sleep on the Hook
I'm not going to comment on whether it's a hook, book, crook, synopsis or study of thanatosis.
I'm going to comment on whether it's an effective hook. You can write haiku... if it works.
