Have you ever written a character interview? They’re great for introducing the people in your story to potential readers and fans. Who doesn’t want to get to know someone who’s interesting? Someone who has already read your story will enjoy getting to know your characters better as well, especially if they have a favorite.
But did you know they’re also an excellent way to get to know your own characters better? Try it next time you’re stumped about how someone in your story would behave. If you don’t know what he or she will do, ask them! If you’re having to push a character to do something and they’re resisting, find out why as well as what they’d rather do. Sometimes this will result in a plot twist, but it will be more authentic that forcing a character to do something contrary to their nature.
