A luxury skincare launch. Three million loyal followers. And a childhood crush rediscovered under the Spanish sun.

Dr. October Reign, a lead archivist for the Center for Brooklyn History, and her family have arrived in beautiful Madrid for the highly anticipated international premiere of Reign Oro—the crown jewel of April Reign Auraverse.

As a rising skincare and lifestyle influencer, April Reign has over three million devoted followers, "The Auras," who are waiting breathlessly for the launch.

But beneath the sun-drenched Madrid sky, a saboteur lurks in the shadows.

To save her sister April's reputation and protect her growing empire, October must trust her senses. The only clues are a slight discrepancy in an import weight sheet and a scent that is just a fraction "off"—a missing earthy note that fails to blend with the signature lemon essence.

While untangling the web of corporate sabotage with her loyal Balinese cat, Oregano, October finds her heart pulled back to the past.

Rafael De la Vega—her childhood crush from when they played in her grandparents' Spanish olive groves—is back in her life. Seeing him for the first time in eighteen years turns up the heat in ways she never expected.

Can October expose the botanical saboteur before the tainted product reaches the public, or will a single drop of deception ruin the Reign family legacy forever?
