In my time travel novel titled "Love Remains" the hero's family, Tom or Tomislav Medar, is from Croatia, while the heroine, Olivia Owen is Canadian
This is totally out of her character. She is all business and career. She believes marriage and family will only hinder her climb up the corporate ladder.
When she returns home from a business trip, she finds exactly what most terrifies her, a husband and two kids. She is undeniably attracted to him, yet she tries anything in her power to get rid off him and the kids.
Tom's gentle yet firm persuasion in both bedroom and the kitchen changes her mind and the idea of being a wife and a mom starts to grow on her. And at first she is jealous of Tom's closely knit family whose values are rooted deep in the culture and traditions, but by opening her heart to him, she too learns to accept and respect every person.
