In a world of scientific certainty, she was the one variable he could never predict—or resist

Devoted to discovery…

Lord Constantine Kellinggrave lives for his scientific experiments, not the frivolities of London society. His meticulously ordered days and silent laboratories provide all the companionship he requires—until an infuriating wager forces him to employ a sharp-tongued scrivener whose presence shatters his carefully constructed solitude. With each passing day, Faith Roth’s intrusion into his sanctuary becomes his greatest annoyance and his most fascinating study.

Determined to succeed…

Faith Roth has fought too hard for her position as a scrivener to be intimidated by her new employer’s stiff demeanor or piercing gaze. The brilliant but reclusive lord may disapprove of her unconventional ways, but she refuses to abandon the independence she’s struggled to achieve—even as his presence makes her question what she truly desires. His laboratory may be methodical, but the chaos he creates in her heart follows no logical pattern.

An unexpected alliance…

When whispers of impropriety threaten their reputations, Constantine and Faith reluctantly agree to a fake betrothal. But as pretense gives way to genuine feeling, their carefully maintained facade begins to crumble. With Society’s expectations closing in, hidden adversaries plotting their downfall, and their own fears standing in the way, they must risk everything they’ve built. As danger and desire intertwine, they discover that the most perilous experiment of all might be surrendering to love.

Between his meticulous calculations and her defiant independence lies an unexpected truth—sometimes the most brilliant discoveries happen when the experiment fails completely.
