Three years after the events of The Golem's Eye, the young magician Nathaniel is an established member of the British Government. But he faces unprecedented problems: foreign wars are going badly and Britain's enemies are mounting attacks close to London.

Two years have passed since young apprentice magician Nathaniel became famous by foiling the ruthless Simon Lovelace. Now 14, Nathaniel is ambitiously climbing the ranks of the magicians' government. The Prime Minister himself has placed Nathaniel in charge of capturing the Resistance, a group of unruly commoners working to undermine the magicians' empire. But after several failed attempts, Nathaniel is forced to admit he can't do it alone.

Nathaniel is eleven-years-old and a magician's apprentice, learning the traditional art of magic. All is well until he has a life-changing encounter with Simon Lovelace, a magician of unrivaled ruthlessness and ambition. When Lovelace brutally humiliates Nathaniel in public, Nathaniel decides to speed up his education, teaching himself spells far beyond his years. With revenge on his mind, he masters one of the toughest spells of all and summons Bartimaeus, a five-thousand-year-old djinni, to assist him.
