A Model of Devotion(Lumber Baron's Daughters‪)‬

She's finally claimed her independence … how far will she go to keep it?
A brilliant engineer, Jilly Stiles has been educated since childhood to help run her father’s lumber dynasty. With the company safe from her stepfather after the marriages of her two sisters, Jilly can now focus on her dream of building a mountaintop railroad—and never marry.
Nick Ryder came into Jilly’s life when he saved her mother from her no-good stepfather, and he’s prepared to protect Jilly from anything that threatens to harm her—as long as he keeps his heart from getting involved.
But when a cruel and powerful man goes to dangerous lengths to make Jilly his own, she must make a decision between her safety and her hard-won independence.
