Ptolemy's Gate (The Bartimaeus Trilogy 3)

"Ptolemy's Gate" is the third and final book of the Bartimaeus Trilogy, following "The Amulet of Samarkand" and "The Golem's Eye". The story starts three years after where "The Golem's Eye" left off, and John Mandrake (Nathaniel) has risen rapidly to the position of Information Minister, engendering jealousy among more veteran members of the government. Instead of dismissing the djinni Bartimaeus, so that Bartimaues could recover, Mandrake has kept him continuously in this realm, leaving Bartimaeus very, very weak. Just as Bartimaeus is reaching the point where remaining on Earth could drain him fatally, a major plot to overthrow the government begins to surface.

Meanwhile, the former Resistance member, Kitty Jones, has taken on an assumed identity, as many people, including Mandrake, think that she perished at the hands of the golem, three years ago. Kitty has begun working for a magician, and secretly studying how to summon Bartimaeus, as she felt that he could tell her much that might help the commoners. Kitty pieces together Bartimaeus's past, which turns out to be quite interesting indeed.

Some consider the following statement to be divulging too much of the plot: Mandrake finally finds Kitty, just as the coup attempt starts, with an outcome that has consequences that are, in the context of this fictional universe, truly dreadful and catastrophic. Will any of them survive? I will say one thing: someone important does die, quite nobly. However, I will also say that, by the time the death occurs, there are several solid hero candidates.
