Where do you get your story ideas? It is the question most often asked of writers. I get story ideas from everywhere. I may be driving in the country and see an old cross of the top of a hill and suddenly I have to know the story of the cross and why it's there. But since I'm driving and may never come back that way...well, I make one up. I might pass an old run down house that looks haunted...yep, new story.
I might over hear a conversation on a bus or the train and suddenly a story comes to mind.
News stories can create stories-for example a man discovered an old Anglo Saxon treasure horde buried on a farm using his metal detector. Boy that's ripe with story- What/who left the treasure? How was it collected? Most of it is male oriented-belts, hilts and souvenirs. Suddenly a Saxon leader is born in my head and the story of how he gathered the horde and what eventually led him to bury it. Or a contemporary story of a treasure hunter who discovers a horde-then instead of turning it in-he hides it...until the bad guys discover what he's hidden...then you have a thriller-
Stories ideas are everywhere. They begin with the questions what and who--what would happen if she left he husband and took a journey around the world. Who would bury a can full of cash under a tree. What if you were the only person alive? Who buried a rune stone under a popular tree in Minnesota?
So, story ideas are everywhere. The key is to discover which ideas have the potential to become books that will sell. The only way to know that is to study the market place. Study the genres you love to read. Study the current trends. Research publisher's guidelines, editor's blogs, agent's tweets and pay attention to what they are looking for. Then figure out which story idea has the potential to sell. Write that story. Cheers!
