As a young girl climbs the seven stories to her own (very boring!) apartment, she imagines what's behind each of the doors she passes. Does the door with all the locks belong to a family of thieves? Might the doorway with muddy footprints conceal a pet tiger? Each spread reveals-in lush detail-the wilds of the girl's imagination, from a high-flying circus to an underwater world and everything in between. When the girl finally reaches her own apartment, she is greeted by her parents, who might have a secret even wilder than anything she could have imagined!
