The Web of Wizardry — Juanita Coulson

The invading warriors appeared from nowhere -- an implacable horde that ravaged the lands of Krantin, slaying and taking their own death wounds in eerie silence. The outer islands had fallen, and soon the sorcery-driven soldiers would be striking at Krantin's heart.

The only hope for survival lay in an alliance of Royal forces with the fiercely independent desert marauders, the Destre-Y -- and with a perilous linkage of all of Krantin's adepts of magic.

The young Troop-Leader Danaer, Destre-born but sworn to Royal service, was the key to the uneasy partnership of ages-old enemies. But his love for the enchantress Lira imperiled the final confrontation between the malignant enemy sorcerer and the protection of the web of wizardry.
