The defeat and death of the evil Wulfgar should inspire a time of rejoicing throughout Eutracia. But Prince Tristan grieves. Not only is his beloved wife dead, but across the Sea of Whispers, in the island fortress known as the Citadel, Wulfgar’s bride, the sorceress Serena, plots to continue her husband’s nefarious plans, aided by the Scroll of the Vagaries and the advice of the otherworldly Heretics. Although the ranks of Tristan’s faithful soldiers were decimated in recent battle, the prince nevertheless plans a bold surprise attack. But on the eve of the mission, disaster strikes. From behind the towering azure wall of magical energy in the forbidding face of the massive Tolenka Mountains comes Xanthus, a powerful warrior dispatched by the Heretics to bring Tristan into their mysterious realm. A master of a mystical martial art against which even the great swordsman Tristan is helpless, Xanthus launches a reign of terror against Eutracia’s innocent subjects, compelling Tristan to journey behind the azure wall. There, in a magical land as beautiful as it is violent, Tristan will learn the shocking truth about the destiny he and Shailiha, his sister, will share. In Tristan’s absence, Shailiha must lead the fleet of Black Ships against the Citadel, accompanied by the wizards Faegan and Wigg and the beautiful pirate queen Tyranny. But unknown to them, Serena has prepared a deadly trap with hellish creatures summoned by the Heretics. And as Shailiha’s troops sail blindly into danger, Serena is preparing a spell unlike anything the world has ever seen–a spell powerful enough to defeat death itself.
