As any writing is tough enough
Without you forcing something through
That “fits the market” or some such stuff
Agents and publishers can tell
If you try to “fake” work just to sell
What they want is your unique voice
And a great story, then they rejoice!
Though the cynical would say what they want is something different but at the same time the same or very similar to works they’ve sold before! However all are agreed about the unique voice bit!
Can you say what is your story?
Do you know its genre and form?
Is it fantasy, sci-fi, gory?
Do all of your characters “perform”?
Do their lives seem real?
Are their motives strong enough?
Is your tale the real deal?
Or is it lightweight fluff?
Though it should be noted even lightweight fluff needs to be well written. Your work needs to grip and convince for it to stand any chance of success. The characters seeming real and not artificial (though of course they are) is crucial.
