Being the mixed race bastard of a Royal duke can be surprisingly boring, but a clandestine trip to the American colonies in the company of her cousin Queen Charlotte is anything but. Grace is looking forward to her one great adventure, but assassins, mechanical killers, an exploding airship and treason a plenty are a little more than she bargained for. With the constant distraction of a handsome Frenchman who is most definitely more than he appears, Grace must navigate both the perils of the colonies and the dangers to her own heart. When duty wars with desire, can Grace find a path to satisfy both?
