Kelly Barnhill, who recently won the Newbery Award with her middle grade book The Girl Who Drank the Moon, talked about the book's origins in Publisher's Weekly. She said an image of a swamp monster spouting poetry sparked the story idea. That image percolated and mixed with her interest in how people see the same thing differently, and her setting was inspired by a trip to Costa Rica.
I think most stories evolve like that. A seed's planted, then another and another, growing a jungle of words in our heads. They have to get along at some point, come together in a cohesive way and they have to make us ask "what happens next? That's when our fingers start typing.
The book I'm working on now started with drawings I did of fantasy figures I saw in the wood floor of an old house my husband and I were restoring. I imagined a lonely girl finding those figures and the story was born. Another book grew from a longing to commemorate the days I spent riding and training horses and the last book sprang from living in a dynamic urban neighborhood.
I like to hear the main character's voice in my head before I start, but I'm not always that lucky. Sometimes, I have to write for a long while before that voice emerges. Since I'm a visual person, setting is vitally important. I need to see the world first, to understand the geography, the buildings and environment. If I try to write without that, the world doesn't feel real.
My critique partners and I have discussions about describing our characters. Should we be specific, so readers have clear visuals, or should we be vague so more people can identify with the characters. I rarely know much about my character's physical description at the start of a story. For me, physicality is not nearly as important as personality.
Let's not forget plot and conflict. It's what drives the story and I've learned the hard way not to start a story without knowing the protagonist's goal. If you have a story screaming to be written and you don't know the main conflict, take a deep breath, take a walk, take the time you need to figure that out. Explore issues that are important to you, like Kelly Barnhill's interest in the way people's perspectives color their world. Ask yourself how your interests and concerns might shape your character's world. Then ask what your character wants and what's the worst thing that could happen. Now, you have the start of a solid story.
