The Reaver Road:

Omar had been everywhere and seen everything, but he had never met a god. Thus, when the Vorkan Horde overran the Spice Lands, Omar hurried to Zanadon because it was well known that whenever that ancient city was in peril, its patron god Balor would return to earth to lead its armies in person. That was the plan anyway...

Reviews:

Aristocratic skullduggery, priestly manipulation, and the affairs of a damsel in distress, in a plot that rushes headlong through a handful of nights and days with many a devious turning. Locus

Omar is not what he seems, and in due course, neither are most of the rest of the characters. A wild and wacky fantasy adventure. Science Fiction Chronicle
