The most dangerous boy in the world?
Timothy is a freak, a weakling, an impossibility. He's the only person in existence without magical powers and has spent his entire life hidden on a remote island. When Timothy is finally taken back to the city of this birth, he is fascinated by the current of magic that fuels the world, and mesmerized by the buildings and orbs that hang weightlessly in the sky. But he is also marked for death.
Assassins are watching his every move, and the government wants him destroyed. Timothy can't imagine what threat he could possible pose; after all, he wields no power in this world.
Or does he?

Book 4

Is this the end?
Timothy and Cassandra may have beaten the evil sorcerer Alhazred, but their problems aren't over. Alhazred was so tied to the matrix of energy that his death caused a magical brownout, dimming all the sorcerous power there is, both in people and in lights. The brownout also caused a weakening in the dimensional barrier that kept the Wurm out of Arcanum. For the first time in decades the Wurm have the chance to exact their bloody vengeance upon the mages who sought to destroy them. Can Timothy and Cassandra end the feud before the Wurm devastate Arcanum?
