Icefalcon's Quest (Darwath #5)

Chaos reigned in the Eastern Lands: as the fearsome Alketch army mounted siege, the young Prince Tir was snatched from the heart of Dare's Keep. Behind the terror was the depraved, hook-handed general Vair na-Chandros. He had learned that the royal child possessed forbidden wisdom; a secret the bloodthirsty Vair intended to use to conquer the world.
One man posed a threat to Vair's vaunting ambition: the legendary warrior known as the Icefalcon. Banished by his own people and scorned as a barbarian by others, only he could hope to free the boy from Vair's clutches. With his sister Cold Death--a sorcerer whose magic was as sharp as her tongue--the Icefalcon embarked on a dangerous mission of rescue and redemption that would force him to wage his greatest battle . . . for his prince, for his honor, and for all eternity.
