Show Don't Tell
The days of writing lengthy prologues filled with pages of backstory to begin your book have long passed. Readers don't want to listen to you lecture or tell about your characters. Today's fiction readers want to get right to the meat of the story.
How often have you picked up a new book and stood reading it in the aisle of a book store only to drop it back on the shelf after the first paragraph? As a writer, if you haven't grabbed your reader's attention right off the bat with an inciting event, chances are they'll move on to a more interesting read.
The best way to pull a reader into your story is to show them what's happening through dialog and action. You can feed them little bites of backstory as they read on, but only enough to move the plot along. Readers don't want to sit and chew on a tough piece of steak forever, they want to move on to dessert!
Certainly, set the scene so your reader can visualize where the action and dialog are taking place, but then get out of the way and let the mind movie roll. The Game is On!
