The Golden Tomb

From publisher blurb: The Golden Tomb: The Bezian Empire survives on loot it prizes off the various peoples it has conquered, and one of the sources of that loot is raiding the tombs of the conquered people's ancient kings. On the far northern fringes of the Empire, the Imperial Army has latched onto a prize prisoner, one who may know the location of the burial mound of one of her tribe's greatest kings – a tomb that is rumored to be filled with riches beyond the dreams of avarice, including a famed chariot of gold. ...Now, if only the army can “convince” the prisoner to lead them to the loot.
