Royal Assumptions - Royal Assumptions, #1

Heir to the spare, Princess Minette has always lived in the shadow of her family. Minette's world forever shifted when her parents and aunt were killed in a devastating plane crash that shocked the French Kingdom. Raised by the Dauphin of France, Princess Minette was groomed to be intelligent, kind, honest, and loyal to her country, people, and most importantly the monarchy. Seeking a chance at normalcy, Minette registers at the University of Oxford, where she realizes that casting assumptions is easier to do from the other side of the glass. She falls first. Regulus is the third-born son of the current Prince of Wales.
Unlike his siblings, Regulus rebels against the firm and all it stands for. The Queen of England will stop at nothing to ensure the future of the monarch. The Queen offers Regulus, an ultimatum. Reel in his wild tendencies and become a full-time working member of the family, or risk being cut off.  Striking a deal to buy himself more time, Regulus agrees to continue his education at Oxford, where he learns more than his program guaranteed. A Prince of England falls for no one.
