Anyone driving alongside Kimberly Killion as she commutes to work from Jerseyville, Ill., to St. Louis on weekday mornings probably thinks Killion is crazy.

Behind the wheel of her 2007 Pontiac G6, she appears to be engaged in conversation with herself, talking, laughing and occasionally crying to no one in particular.

But what the other drivers on Interstate 270 might not see is her palm-sized digital recorder, which is capturing dialogue between a hero and heroine who "fight, play, laugh and sometimes say something so funny I laugh out loud," Killion said.

"You have to have skin 2 inches thick and more guts than a 500-pound hog. It's a tough market. Everyone thinks she or he can write romance, but if you aren't a reader who really loves the genre, you won't write it well."

"Life's too short to spend so many hours on the road alone. Why not share it with someone, even if that someone is a fictional character?"

Killion writes romance novels, and the drive to work is just part of her daily writing routine.

According to the Romance Writers of America, romance is the largest selling genre in fiction. Killion is one of thousands of women (and a few men) across the country and hundreds in Missouri — accountants, teachers, engineers, stay-at-home-moms — who aspire to create their own happily-ever-after tales.

Kimberly Killion's first published novel, "Her One Desire," is a historical romance set in 1483 England to be released by Kensington Books in July.

It tells the story of a lord high executioner's daughter who discovers a conspiracy that puts her in danger. The only man willing to protect her is the Scottish spy she frees from her father's prison. Romance novels like Killion's are relatively brisk reads, as well as guilty pleasures — $4.99 impulse buys from the grocery checkout line that can offer escape from reality, companionship aboard an airplane or beside the pool or mind-numbing reward under cozy sheets after a grueling day.

But writing them is another story. The novels may be breezy or formulaic, but the process of becoming a published romance author is not.

Killion's nonstop artistic passion and exhaustive writing schedule offer a glimpse into the time, energy and emotional commitment needed to excel in the genre.

Her typical day begins around 4 a.m. when she wakes up and writes until about 6, then gets ready for the rest of the day.

Around 7 a.m. she puts her two children on the school bus, then leaves for work. Her commute offers about an hour each way to develop her characters.

Returning home from teaching graphic design at a St. Louis college, she sits down at the keyboard, presses "play" on the recorder and types away, producing somewhere between 1,000 and 2,000 words of romantic fiction every day. She doesn't turn off the lights until midnight.
