Tyler and Charles Carnegie were just boys when their father, King William of England, was assassinated in front of them by IRA terrorists-but history doesn't allow time for grief or a normal childhood when you're in line for English throne. Thrust into the life of English royals, the two American teenagers have the eyes of the world upon them. At just age 17 and first in line, Tyler is crowned King Charles II. Overwhelmed by the responsibility, King Charles struggles to win over the hearts of his new subjects, volunteering for the most dangerous duty and working hard to be the people's true king. His brother Henry, wild at heart and only 16, fights the strict life of a royal at every turn, his handsome face gracing the cover of tabloids all too often after another one of his pranks, until finally he is expelled from Eton, the snobby British prep and demands to return to the United States. Continents apart, the boys are thrust into a fight for their family's honor, the crown, and their very lives as powerful forces deeply embedded in the British aristocracy work to eliminate these upstart Yankees. As the trap closes in, the boys have only their wits and each other to rely on as they fight to save everything they've ever loved.
