The Rogue's Last Scandal (Sons of the Spy Lord)

Like any good rogue, he was after a lady. Saving a young heiress from being wed to a scoundrel might just ease Charley Everly’s boredom with his current assignment. He’s been looking for a lady: beautiful, rich, Spanish, and the key to a traitor. Could Grace Kingsley be the one? Falling—literally—into the arms of the ton’s most outrageous rogue seems a risky path of escape, but Maria Graciela Kingsley y Romero has no other choice. Only the great Earl of Shaldon can help her, and he is not to be found. So his son will have to do.
