The Butterfly and the Baron (1979)

She would choose her own husband! When Renee's wealthy parents arranged her marriage to a man she despised, she had fled to her beloved Aunt Katie's home in Queensland. There she had hoped to escape and recover her shattered pride, but her plans were crushed by Nick Garbutt, a man even more powerful than her father. Nick had the ability to arouse in her all the emotions she'd been accused of lacking -- emotions she now felt ill-equipped to handle. Especially knowing that Nick was to marry someone else!
