From Holly Black and Cassandra Clare comes the second installment in the New York Times bestselling series -- Now in Paperback

Callum Hunt's summer break isn't like other kids'. His closest companion is a Chaos-ridden wolf, Havoc. His father suspects him of being secretly evil. And, of course, most kids aren't heading back to the magical world of the Magisterium in the fall.

It's not easy for Call . . . and it gets even harder after he checks out his basement and discovers that his dad might be trying to destroy both him and Havoc.

Call escapes to the Magisterium -- but things only intensify there. The Alkahest -- copper gauntlet capable of separating certain magicians from their magic -- has been stolen. And in their search to discover the culprit, Call and his friends Aaron and Tamara awaken the attention of some very dangerous foes -- and get closer to an even more dangerous truth.

As the mysteries of the Magisterium deepen and widen, bestselling authors Holly Black and Cassandra Clare take readers on an extraordinary journey through one boy's conflict -- and a whole world's fate.

All his life, Call has been warned by his father to stay away from magic. Now that he's entered the Magisterium, Call's sure the school can only bring bad things. A place both sensational and sinister, the Magisterium has dark ties to his past -- and a twisty path to his future. A path that will forever change everything Call thought he knew about the worlds of good and evil.
