In Thief of Souls, the survivors -- now five -- will confront a more insidious but equally terrifying foe, The Bringer. Imprisoned for thousands of years by the ancient gods, The Bringer bides his time. When finally he breaks free and invades the world through a breach in the universe, only one power exists that can stop him from taking his revenge: the surviving Star Shards. The Bringer must destroy them. But how? Together they are too powerful to confront and defeat in open battle. The Bringer seduces them in an attempt to turn one upon the other -- like hungry snarling wolves.

Only these wolves have the power to destroy the world.
