Tips for Choosing a Good Title:
* Consider the genre: A noir thriller might have a more atmospheric title than a police procedural.
* Think about the main theme: Is it betrayal, revenge, justice, or something else?
* Keep it short and memorable: Readers should be able to remember it easily.
* Make it relevant to the story: Don't use a title that's too vague or doesn't reflect the content.
* Test it out: Read the title aloud to see how it sounds.
Remember, the best title is one that captures the essence of your story and intrigues potential readers.
