The Rules of Royalty by Cale Dietrich

Will Jamie be bound by duty or follow his heart? The Princess Diaries meets Red, White and Royal Blue in this deliciously royal queer YA romance from the bestselling co-author of If This Gets Out.

Jamie expected a cake, not a crown, for his seventeenth birthday, but when he finds out he is the prince of a tiny European country called Mitanor, life will never be the same.

Erik, the spare heir of neighbouring country Sunstad, is feeling stifled and miserable as his golden-boy brother prepares to get married. So when he's offered the opportunity to teach an American how to be a prince, he leaps at the chance.

But in between garden parties, balls and lessons in royal etiquette, sparks fly between the two princes, and they are forced to choose between love and duty.
