Prince Louis is the oldest child of the King and Queen of Arcadia and is preparing to take the thrown after his father's thirtieth and final year. He is already feeling anxious, the ancient tradition of the palace is to have his inauguration exactly one week after his twenty-first birthday. Thankfully his trusted adviser, and best friend, Zayn has been helping him prepare; yet it's becoming increasing difficult to rely on his services when there is a certain stable boy custom to flannel shirts unknowingly stealing his attention. Though it doesn't really matter, no preparation could ease the surprise his father's bestows upon him just weeks before his special day: He has to get married! A legal contract, that was drawn eighteen years previously, states he has to tie the knot with nobility in order to obtain the crown, and to make it worse, with a bloodline that has already been chosen for him. Is he ready to share his home with a complete stranger? He's ready to try if it's for the country he loves to no end. This is the story of next-in-line ruler of Arcadia: Prince Louis, only unmarried child of the Styles family: Duke Harry, chief adviser to the Prince: Sir Zayn, the best friend of the Duke (and happy go-lucky soul): Lord Niall, and the beautiful/sensible stable-boy who gets wrapped up in the palace drama: Mr. Liam Payne.
