After Princess Isabella's wedding gets crashed by an old enemy of her sister, Princess Harper, and her spy squad, she is forced into the world of espionage, secret missions, and magical mansions. There is a whole life outside of the castle, and Harper has lived far more of it than Isabella, becoming a hero behind the shadows of the castle throne. All Isabella wants to do, however, is survive her stepmother's wrath and find out what really happened to her father when he was found dead in his royal chambers all those years ago. Will Harper convince her sister to join the squad and be free of her royal restrictions? Will they get back the bond they lost when the King was murdered all those years ago? Or will the return of the squad's old enemy bring with him more chaos and bloodshed than he first did several years ago, resulting in the squad being played like puppets through his deceit and manipulation? "This isn't the story where the prince rescues the princess."
