A hidden genius, an ambitious shipbuilder, and a daring deception—can she prove her worth without losing her heart?

Eli Kennebrae plans to revolutionize cargo transportation on the Great Lakes. But his grandfather's meddling obligates him to an arranged engagement. Though Josie Zahn is kindhearted and strikes his interest, Eli needs an engineer for his ship, not a fiancée.

Josie has admired Eli for years, but to him, she’s just “one of the Zahn girls.” Worse, society expects her to marry, not pursue her passion for mathematics and engineering. If she could only get Eli’s attention, she could help him achieve his goals.

Then “Professor Josephson,” a brilliant mathematical mind, provides the analyses to make Eli's ship design a reality. As Eli finds unexpected kinship in the professor’s work, he remains unaware of the truth—Josie is the genius behind the numbers. When deception and ambition collide, will Eli see Josie for who she truly is before it’s too late?
