Who doesn't love art? Simon and Sophie, that's who. The cousins ditch their class tour of the museum because art is BORING. But, while exploring all the rooms and corridors on their own, they enter a world of mystery and suspense. This fantasy picture book for the seven to ten year old takes Simon and Sophie on a personalized tour of the museum by one of its sculptures. Arthur, who was turned to stone with his grandfather years ago, comes to life when the cousins enter the room his exhibit is in. After Simon and Sophie recover from the shock, Arthur shows them all the wonders the museum holds. But once the tour is over, he has to go back into the sculpture. Just before he freezes in place, he tells the cousins what they can do to help him and his grandfather become alive again . . . and stay alive.
