A royal disaster...
Arthur Castle, an exchange student from a small country called Santa Dora, is coming to Sweet Valley Middle School and the sixth graders can't wait! They have planned all kinds of welcoming events and parties for him.
Arthur doesn't want anyone to fuss over him. He wants more than anything to be treated just like any other boy. He also wants to discover what real American kids are like. When Arthur meets Elizabeth Wakefield, his dream comes true. Their friendship grows quickly, and soon he even tells her his deepest secret—that he is actually a prince!
The next day his secret is all over the school, and Arthur is furious. He thought he had made a true friend in Elizabeth. How could she betray his trust!
