"Full Steam Ahead" by Karen Witemeyer

Darius Thornton has become known as the eccentric, reclusive scientist who blows things up on his isolated property. The boiler explosion that he witnessed two years ago has made him withdraw from most society and devote his life to experimentation and solving this particular steam engine problem.

Fiercely independent Nicole Renard fled her home with her family's most treasured possession secreted away. Her ailing father had sent her on a quest to New Orleans to find a husband and an heir for his business, but those out to steal the treasure forced Nicole to change plans. Desperately needing to hide away and earn some money to continue her quest, she finds herself applying to be Darius Thornton's secretary.

The two strong-willed characters butt heads but are also quite attracted to one another. Darius has never met someone so determined and able to stand up for herself. Nicole is drawn to the troubled man but tries to keep her distance so that when she leaves her heart will be free to fulfill her father's mission.

Those seeking the family treasure can't be thrown off Nicole's scent. Darius and Nicole must work together to save her family legacy, while also convincing the other of their true affections and intentions. It's one explosive turn after another to see how this story will play out.
