Edge of the World — Christie Golden

Seven years ago the Hero vanquished the threat across the sea and claimed his throne. As King he led Albion to an era of unprecedented peace and prosperity. But on the night of his wedding to his new Queen, ominous word arrives: The Darkness has returned.

Beyond a harrowing mountain pass, the exotic desert country Samarkand has been overrun by shadowy forces. Within the walls of its capital city, a mysterious usurper known only as the Sultana has seized control. To protect his realm, the King must lead his most trusted allies into a strange land unknown to outsiders. As they forge ahead along Samarkand's ancient Great Road, populated by undead terrors and fantastic creatures once believed to be the stuff of legend, the King is drawn ever closer to his greatest challenge yet.

But soon Albion is engulfed in a war of its own. As the Darkness spreads, town by town, a treacherous force has infiltrated the Queen's circle. Now the fate of all that is good rests with a faint flicker of hope . . . that somewhere, somehow, heroes still do exist.
