The final, thrilling instalment in this extraordinary series from bestselling authors Holly Black and Cassandra Clare.

A generation ago, powerful mage Constantine Madden came close to achieving what no magician had ever achieved: the ability to bring back the dead. He didn't succeed . . . but he did find a way to keep himself alive, inside a young child named Callum Hunt.

Facing up to what he is, Callum has battled chaos and evil across four years of magical training at the Magisterium, eventually defeating the armies of chaos in an epic battle.

It came at a cost.

Now, triumphant and heartbroken, Callum Hunt has just about had enough, and is ready to complete his training. But the evil Callum faced has not given up just yet . . .

Callum Hunt's life has fallen apart.

His friend is gone. The spy has escaped. His secret is out.

He is facing an existence behind bars, banished from the rest of the magical community for what he is - for what he might become.

But a shocking revelation has promised freedom - at a cost. Will he stay strong, and faithful to his friends and teachers? Or take the risk, and destroy everything he's ever loved?

This fourth year at the Magisterium will be unlike anything else that has gone before . . .

Magic can save you
Magic can kill you

It should be a time of celebration. The Enemy of Death is dead; a severed head proof of his downfall. The magical world has no reason to believe otherwise, and Callum, Tamara and Aaron are celebrated as heroes.

But at a party held in their honour, things go horribly, brutally wrong. A fellow student is callously murdered, and it seems Call's worst fears are confirmed: there is a spy in the Magisterium.

No one is safe.

Now, using the powerful magic they've been taught, the trio must risk their lives to track down the killer. But magic is dangerous - in the wrong hands it could bring terrible destruction. And reveal the deadliest secret of all . . .

One boy . . . One dragon . . . A world of adventure.

When Eragon finds a polished stone in the forest, he thinks it is the lucky discovery of a poor farm boy; perhaps it will buy his family meat for the winter. But when the stone brings a dragon hatchling, Eragon soon realizes he has stumbled upon a legacy nearly as old as the Empire itself.

Overnight his simple life is shattered and he is thrust into a perilous new world of destiny, magic and power. With only an ancient sword and the advice of an old storyteller for guidance, Eragon and the fledgling dragon must navigate the dangerous terrain and dark enemies of an Empire ruled by a king whose evil knows no bounds. Can Eragon take up the mantle of the legendary Dragon Riders? The fate of the Empire may rest in his hands...
