The Paladin of the Night (Rose of the Prophet, Book. 2)

The Great War of the Gods means nothing to the  proud people on the mortal planet--until Akhran the  Wandering God decrees the union of two mighty  feuding clans. Though the families are fierce  Warriors, they are few in number. Even the marriage of  Khardan and Zohra is not enough to over power the  strength of the invading army or prevent the  imprisonment of their peoples. Now, with Khardan and  Zohra mysteriously missing--seemingly cowards who  hid from certain defeat--the two clans have lost all  hope of ever again seeing their beloved open  skies. But Prince Khardan and Princess Zohra, aided by  the wizard Matthew, have been given another  mission...a mission that at first seems less useful  than counting the many grains of the desert sands,  but soon proves to be of far more lasting  importance.
