Sherri Chan is an independent, smart, successful woman. As the youngest member on the faculty of a small college, she has always taken pride in her ability to rise to any challenge, until her boyfriend proposes and her life goes into a tailspin. Caving into the pressure, she accepts, knowing that she doesn't love the man she has promised to marry. Her feelings are complicated by a chance meeting with a good looking cowboy, who Fate keeps throwing in her path.
The only one who seems to understand is her twin brother Sherman, but he will soon return to his home in Toronto, leaving her to deal alone with family expectations, and her own floundering faith.
