I'm looking for the title of a novel I read 10 years ago that takes place in the United States.
It follows a young boy who believes he is a nobleman. He is isolated in a castle with servants.
We later discover that his "parents" have kidnapped him, (this couple work in theater or cinema, they can't have kids so they use to kidnappe little boys until they turn 11 years old).
He lives in a world reminiscent of a movie set, and his servants are also kidnapped foreign children.
The police arrest them, he is placed back with his family, including a very religious character named Jedediah who mistreats him. He eventually escapes and experiences many more misadventures.
I'm sorry this is very messy information, but if anyone can find the title, that would be amazing.
