King of the two lands

There is an intruder inside the Royal Palace. The only person who can see him is the King—a fifteen-year-old boy who, until a few hours ago, possessed no powers at all. Marwan is the sovereign of the United Kingdom of Egypt and Sudan. On the day of both his engagement and his birthday, the thing he fears most is about to arrive in the form of a visitor. Ten years ago, he made a promise to his childhood friend: when they met again, they would show each other their powers and how far they had progressed. But only minutes before she arrives as his fiancée and the future commander of the Royal Guard, the young king still possesses no power whatsoever. Everything changes when he is presented with the jewel of the nation's greatest heroine as a birthday gift. A strange voice begins whispering in his ear. An intruder that only he can see has infiltrated the Royal Palace. As Caliph of the Faithful—the highest religious authority in his nation—Marwan must make a choice: Should he reveal what he sees and hears, or remain silent for fear of being branded as one possessed?
