This is Book Two in the trilogy, "The Pendragon Cycle". From the rear cover: "Peace has blessed Mensandor for ten glorious years, ever since brave Quentin helped the Dragon King reclaim his throne. But now the great liege is dying...and an ever-brightening star shines above the kingdom-an omen of dire evil at large in the southern lands. For Nin the Destroyer has come with his barbaric hordes to ravage and rule. And once more Quentin has been chosen by destiny to save the realm...to travel great distances on perioous paths...and to forge a weapon foretold by prophecy: the mighty sword called the 'Zhaligkeer'."
