Andrea here, musing today about secondary characters. I find that one of the ways to keep a series fresh and engaging for readers is the addition of new secondary characters in each book. Not only do they add to plot twist possibilities, but they also add color and texture in their interactions with the main protagonists, allowing me to bring out facets of the “stars” in interesting ways. (Though often they aren’t really content to hover in the shadows, but get a bit pushy and keep demanding more time on center stage! Honestly, don't they know who's the boss here?)
It’s great fun to sit and think about what sort of friend will add to the mix of a story. It’s hard for me to explain how they come to mind . . . sometimes—like the fog in Carl Sandburg’s famous poem— they come in on little cat feet . . .
