I recently completed the process of rewriting and revising what I hope will be my debut novel. Since beginning this project over ten months ago with a blank computer screen, I've learned some interesting lessons about creativity and the writing process. Thus, my first Novice Novelist Novel Note (4N), highlighting characters.
Characters Who Don't Go Away More than one character that I created for a specific story purpose has stayed around, popping up periodically to create mischief or solve a sticky-wicket-plot-knot (more on that in a future 4N). The first character who refused to leave has become an integral part of the entire storyline. I've been amazed by his evil ways, but if I'd tried to rein him in, or to shove him out the door, important elements of the story would have gone with him. I figured it was best to just let him keep surprising me with his dastardly deeds.
Characters Who Steal the Show At the end of one chapter I sent my critiquing partners, I wrote a note: "Is it just me, or did Major Bennett completely upstage Marie [the protagonist]?" He most certainly did, but he also added humor and lightness in the midst of tragedy. Best of all, he invited his wife and parents to join in the fun and, also unexpectedly, his actions moved the story forward.
Characters Who Show Up at the Last Minute Since my first tentative beginnings of this story, I knew I needed two specific characters to perform one specific function. But even though I thought and thought (and thought some more) about them -- nothing! Every effort to give them motivation failed. Then, during the last couple of weeks before my deadline, there they were, waiting in the wings to do what they had to do. Yes, they're shy and unassuming, but integral to the story nonetheless. The point here is that these two couldn't be forced, only welcomed at the right time.
As you're creating characters for your story, check to see who's knocking at your novel's door. Whether they hang out longer than you expected, steal the show, or come late to the party, welcome them with open arms.
