Jagang, Emperor of the Imperial Order, has invoked a bound fork prophecy binding Richard and Kahlan to a fate of pain, betrayal, and a path to the Underworld. At Jagang's behest a Sister of the Dark gains access into the fabled Temple of the Winds and has unleashed a plague that sweeps across the lands like a firestorm consuming lives at an alarming rate. To stop the plague Richard and Kahlan are forced to sacrifice everything they have between them....

Richard comes to terms with his true identity as a War Wizard. The New World, and all the freedom of humankind, is under threat from the Imperial Order after he had brought down the barrier between the Old and New World. The Imperial Order has already sent delegations and armies into the New World. Richard's only option to stop the invasion is to claim his heritage and unite all free kingdoms and provinces under one rule and one command.

A poisoned Richard Rahl faces a difficult choice when he is promised an antidote and the salvation of an endangered empire if he will surrender his beloved wife, Kahlan Amnell, to his enemy.
