We know the importance of making our characters authentic, believable, and memorable for readers. But relevance is important, too, because it makes them relatable. Readers see characters who are facing the same issues they’re facing or dealing with the same struggles they’re dealing with, and a bond is formed.
As an example, look at To Kill a Mockingbird. It was written in 1960, but this story about children navigating a racially-charged culture that is altering their safe and comfortable world is still relevant to us almost 50 years later.
Are your characters relevant?
