The Seneschal — Jay Palmer

Not All Warriors Fight!
Torn from his well-ordered castle, young Galloway is commanded to be the Royal Seneschal, to provide the King's army with food, water, horses, and supplies ... at a distant mountain pass surrounded only by desert. Even before their enemy arrives, Galloway's inadequate resouces earn him hatred from the starving troops and their squabbling commanders. But as the fighting begins, Galloway discovers that victory depends on his non-martial skills as surely as on any soldier, and any mistake by anyone could destroy their only hope of survival.

Thirty years before, Aveleck succeeded from the Kingdom of Brioenth after bloody civil war, and now Brioenth seeks revenge. Vastly outnumbered, Aveleck can't prevail, but where swords are blunted, other weapons must be sharpened ...
