The Golem's Eye: The Bartimaeus Trilogy, Book 2 (Paperback) Jonathan Stroud

The duo is reunited just in time: the Resistance is growing more audacious than ever. And to make matters worse, a seemingly invulnerable clay golem is wreaking destruction throughout London, sending the entire city into pandemonium. With time running out, the young magician and his uncontrollable djinni must find the source of the golem's power, a task they quickly learn will involve much more than they ever anticipated.

In the ensuing chaos, Nathaniel and Bartimaeus will be chased through the streets of Prague, hunt a dancing skeleton across London's skyline, encounter the horror of the dreaded Night Police, and meet a surprising new ally. Together, these three will have to go head-to-head with the fearsome golem before the mysterious identity of its master is finally revealed.
