On Wings of Magic — Andre Norton

Tumultuous changes reverberated throughout Witch World. The witches of Estcarp lay decimated by the massive mountain-moving magic of the Turning, Saving their world from invasion by Pagar of Karsten wreaked a havoc all its own, and the face of the world has been racked by catastrophe. Now is a time of chaos: former enemies are thrust together; ordinary people must become heroes.

A simple scribe holds the key to her village's survival; the parents of a kidnapped girl challenge the mighty Hounds of Alizon, Karsten's ally. Their fight against all odds to defeat the malicious magic of the Hounds is their only chance to win their way to freedom.

This is the stuff of high adventure; memorable, enchanting.
