The tremendous climax of the Bartimaeus sequence. Three years on from the events in The Golem's Eye, the magicians' rule in London is teetering on a knife-edge, with strikes, riots and general unrest.
The Prime Minister is largely controlled by two advisers, one of whom is 17-year-old Nathaniel.
Meanwhile, living under a false identity, Kitty has been researching djinn; she has come to believe that the only way to destroy the magicians is with an alliance between djinn and ordinary people. Kitty seeks out Bartimaeus and embarks on a terrifying journey into the djinn's chaotic domain - the Other Place - which no human being has ever survived.
But even as she does so, Makepeace engineers a dramatic coup d'etat. The outcome is a shattering of the magicians' control and all magical laws are turned upside down.
Can Bartimaeus, Nathaniel and Kitty settle old scores to prevent the earth's destruction?
