'Once, long ago, I was second to none. I could slice through mountains...fell forests with a single breath...'

Two thousand years have passed since Bartimaeus was at the height of his powers - invincible in battle and befriended by the great magician Ptolemy.

Now, trapped on Earth and treated with distain by his master, Nathaniel, Bartimaeus finds his energies are fading fast. With Nathaniel preoccupied by the problems of a failing empire, and more rigid and insensitive than ever, the long-suffering djinni's patience is finally at an end.

Meanwhile, undercover in London, the fugitive Kitty Jones has been stealthily completing her research on magic and demons. She has a plan that she hopes will break the endless cycle of conflict between djinn and humans - but first she must uncover the secrets of Bartimaeus's past.

This extraordinary conclusion to the Bartimaeus Trilogy moves across the centuries and into unknown worlds. With disaster threatening everyone in London, the destinies of Bartimaeus, Nathaniel and Kitty are untwined for a final time. Together, they must defeat treacherous magicians, uncover a chilling conspiracy and face the most dangerous threat in the history of magic.

Worst of all, they must contend with each other...
