Flowers of the West Series by Millie Criswell

Heather Martin longs to become a newspaper illustrator. Unfortunately, in 1830's San Francisco, newspapers weren't interested in hiring a woman to do a "man's work". Forced to work as a nanny for Brandon Montgomery, owner of the city's largest newspaper, Heather quickly comes to dislike this arrogant man. His feelings are mutual, until passion takes hold.

Laurel Martin leaves her hometown in search of a husband, hoping to make her father's deathbed wish come true. She arrives in Denver, determined to sing at its fabulous opera house, but she is the only one who thinks she is qualified to do this.

Even though her father's deathbed wish was for all his girls to find husbands and leave Kansas, Rose has no desire to move. When the farm is sold to the Duke of Moreland, Rose stays on but is unprepared for the passion the Duke brings into her life.
