This is one my favorite books of all time. I read it in 1st grade and could not put it down. Claudia and her brother Jamie run away to live in the Metropolitan Museum of Art because they are bored with their lives. The two children hide from security guards, and museum workers just so they won't be found. They eventually find out that one of the statue's in the museum which was said to be sculpted by Michaelangelo is a fake. The two children have to try and solve the mystery before this fraud goes on for much longer. Read the book to find out what happens.
