Theirs is a strictly business relationship...until it isn't.

Despite his family's opposition, Niall Drummond is going ahead with his plans to renovate and upgrade Bannock Castle. Willa Mae Jamison, a savvy, sassy American property developer, helps him with his plans. She's feisty enough to hold her own against him, and clever and creative in her ideas for his castle. He's attracted to her, but he's not looking to start anything serious. At least, that's what he tells himself, because he refuses to admit that he's fallen for her. Willa Mae Jamison falls head over heels for Niall Drummond the minute they meet, but she doesn't believe in love at first sight. She does everything she can to avoid getting too close to him, but she can't resist his charm. It doesn't help that he's as smart as a whip and seductive as sin. His arrogance and bull-headedness should make her despise him, but with every look and every touch, Niall captures a little more of her heart.

She must find a way to resist him...right? Niall and Willa Mae struggle to get out of their own way long enough to see the truth they both deny. When Niall makes a shocking discovery that complicates his plans, he knows that he must choose Willa Mae or he will lose her and his chance for a happy ending.
