Dragons of a Vanished Moon — Margaret Weis; Tracy Hickman

The flames of war devour Ansalou. The army of dead souls marches toward conquest, led by the mystical warrior Mina, who serves the powerful One God. A small band of heroes, driven to desperate measures, leads the fight against overwhelming odds.

Two unlikely protagonists emerge. One is a dragon overlord who will not easily relinquish her rule. The other is an irrepressible kender who has been on a strange and remarkable journey that will end in a startling and unforeseen fashion.
