First off, consider your target audience. Titles that appeal to them are more likely to draw them in. Then, look for something unique or unexpected. It could be a play on words or a mysterious phrase. But make sure it gives a hint of what the story is about without giving too much away.
Well, you need to think about the core idea or theme of your story. Try to find a phrase or word that captures that essence. Also, make it catchy and easy to remember.
