Magisterium: The Bronze Key - Author Holly Black

A spy in the Magisterium. A student murdered. A secret too dangerous to ignore.

Callum, Tamara and Aaron should be celebrating their victory—the Enemy of Death is gone, and the magical world is safe once more. But everything changes when a fellow student is mysteriously killed at a party held in their honour.

With danger lurking within the walls of the Magisterium, the three friends must unravel a deadly conspiracy. As they search for the traitor, they face powerful dark magic, growing uncertainty, and a truth that could change everything they thought they knew.
