Some story ID questions get wrongly closed as too broad. "Too broad" is typically evaluated on answerability, not length. So if a story ID question really does have a unique, identifiable answer, it should be kept open even if it is short. If a question is wrongly closed, you can vote to reopen (once you have enough rep) or bring it to meta as you have done here.
Unfortunately, the question you linked doesn't look very answerable to me. It does not describe:
- The approximate year in which the asker read the book.
- The genre (which the asker does not know).
- The setting (beyond "in the woods somewhere").
- Any information about individual characters.
- And so on...
I'm having a really hard time believing there is exactly one story which this question could possibly be about. What happens if we reopen it, you post your answer, and then the asker says "No, that's not it"? So personally, I will not be voting to reopen this question.
