Lady Arabella, the beloved daughter of a Duke, has always yearned for a life beyond the gilded cage of London society. When she stows away on a transatlantic voyage to escape a stifling future, she is discovered by the American she is falling for, Nathaniel "Nate" Cross. A marriage of convenience is proposed to save her reputation, but Arabella soon discovers Nate's family is on the brink of financial ruin, and her dowry is their last hope. As their union is born from desperation and a secret, a rival company's deadly sabotage puts Nate's life—and their fragile bond—at risk. With a family's future at stake and a heart on the line, Arabella must fight to clear Nate's name, save his family's legacy, and prove that a life built on a lie can still be a foundation for love.
