Anthony Bonehill plans to outwit a Djinn with his seven accomplices. Six will make their wish, and the seventh must wish the Djinn dead. But the seventh accomplice, Carlos Grossford, double-crosses them and now he can wield whatever tyranny he chooses.

Necessity Bonehill is a tomboy. Being sent to a boarding school for girls has honed rather than tamed her wild side. She fears her parents were keen to get rid of her, and therefore feels abandoned. So when Uncle Carlos starts sending her food parcels, she is happy that someone cares. Then one day he sends a stoppered bottle. Ness is perplexed, but surely there can't be any harm in opening an empty bottle?

She takes out the stopper and unwittingly launches herself into and exotic and cut-throat world as the powerful Djinn is set free, hell-bent on revenge.
