When we begin writing our books, we feel an urgency to catch the reader up, bring them over the hurdles of history in our story. We have a lot of past to pass along. We think this past is essential: If the reader doesn’t know Jane was traumatized as a child, how will she understand why Jane is so careful with her adult relationships? If the reader doesn’t know the entire history of the Scout troop, will he get why the boys are intensely loyal to each other?
But what’s more important—to make sure your reader understands why you are telling this story? Or to get that reader engaged so they'll keep reading?
