The letter in their hands tells a horrible story. The Ghost House is filled to the brim with mentally ill people turning into ghosts - and now Scott and Vienna are going there. But once they arrive at the House, they discover it's not as bad as they think. Scott and Vienna have new friends and allies, and they meet some people they never thought they'd see.
But it's not all fun and games - when Scott and Vienna begin having mysterious dreams and find a stack of papers detailing how to escape, it becomes a race to discover the House's secrets before someone discovers them. Or worse, before they turn into ghosts permanently.
