SOPHIE'S favorite place in the world is the hidden shop beneath her parents' bookstore, where dreams are bought and sold to select and secretive strangers. Sophie is fascinated by dreams-weird, scary, or magical-in part because she has never had a single one of her own. When the shop's dreams are stolen and her mother and father go mysteriously missing, Sophie must unravel the truth to save her parents. Together with her best friend-a wisecracking and fanatically loyal monster named Monster-she must decide who to trust with her family's carefully guarded secrets. Who will help them, and who will betray them?
