Dragonlinks — Paul Collins

An all-powerful, enchanted mailshirt from the stars.
Six links are missing.
An orphan, a streetwise urchin and a swordsman must find the links before the greatest evil known descends upon Q'zar.
Jelindel dek Mediesar led a charmed life until lindrak assassins murdered her family. Fleeing to the markets Jelindel dresses as a boy to avoid detection. Here she teams up with Zimak, a street-wise urchin, and Daretor, a warrior on a quest to destroy an alien artifact.
Murder, betrayal and deceit are just some of the hurdles they must face in order to find the missing links from a star-dwellers' mailshirt -- six powerful links, whose individual powers are nothing compared with that of the complete mailshirt.
