Ptolemy's Gate is the third book in the Bartimaeus Trilogy, written by Jonathan Stroud. It was released in the UK in September 2005, and in the US in December of '05. Three years have passed since the magician Nathaniel (otherwise known as John Mandrake) helped prevent an attack on London that would have been cataclysmic for its magicians and commoners. Now an established member of the British Government, he faces unprecedented problems: foreign wars are going badly, Britain's enemies are mounting attacks close to London, and rebellion is fomenting among the commoners. Increasingly imperious and distracted, Nathaniel is treating Bartimaeus worse than ever. The British Empire is falling apart. Many commoners are unhappy with the current government, though none of the commoners claim responsibility for the status quo. The magician's demons are being assaulted by the children's natural abilities to see and resist the demons.
