Notorious Atherton (Rebellious Sons #3)
Patricia Rice

Nick Atherton long ago retired from his villainous life of piracy, but he’s dragged out of his role as fashionable fribble to protect the princess—rather, the impostor. Nick would far rather seduce the comely widow, but first he will have to dodge French spies and pursue misbehaving royalty.
For the fate of a nation and a princess, Devil Nick takes to the high seas again, but will his illegal exploits cost him the respectable woman who finally captures his heart?
