Life is far from perfect. The last thing people want to read at the end of a long day is how a happy-go-lucky character got a promotion and celebrated with a perfect night out on the town. Readers want to sink into a cozy chair and live vicariously through death-defying characters. To allow the reader to stay safe and sound while experiencing danger and intrigue, writers must take all the risk. Some writers may wish for a nice, pot-hole free tole road, but most of us slash the parachute and dive into a lightning storm, hoping to find a little inspiration.
