Vying for the viscount / Kristi Ann Hunter.

Enhanced descriptions from Syndetics:

For Hudson, the newly titled Viscount Stildon, moving to England from India where he was born and raised was already an arduous enough endeavor. When he learns the fate of the racing empire he inherited along with his title depends upon him getting in the good graces of another stable owner, he's even more at a loss.

The stable at the neighboring estate has been Miss Bianca Snowley's refuge for years, and when a strange man appears to be stealing the horses, she jumps to their protection without a second thought. Upon learning Hudson is actually the new owner, she can't help but be intrigued by the area's newest eligible bachelor.

Any thought of romance is quickly set aside, however, when Hudson proposes they work together to secure suitable spouses for each other. As their friendship grows, Hudson and Bianca begin to reconsider what they truly want in life. But will societal expectations and the weight of their responsibilities keep them from pursuing their true desires?
