Ptolemy's Gate (A Bartimaeus Novel Book 3)

The final book in the Bartimaeus trilogy concludes the story three years after Nathaniel helped prevent a catastrophic attack on London. Now a government official, Nathaniel faces mounting crises: failing foreign wars and growing unrest among commoners. His treatment of the djinni Bartimaeus has worsened, and the weakened demon is losing patience with his time in the human world. Meanwhile, Nathaniel's rival Kitty has been conducting secret research into magic, demons, and Bartimaeus's origins. She has developed a plan to end the cycle of conflict between djinn and humans, though it remains unclear whether others will accept her ideas. As the trilogy concludes, the paths of Bartimaeus, Nathaniel, and Kitty intersect again. The story reveals secrets from Bartimaeus's past and offers glimpses into the Other Place, while the three face corrupt magicians, a complex conspiracy, and a rebellious group of demons.
