The War With Audin — James E. Wisher

The combined military forces of five city states have arrived outside of Audin. They've come to punish the arrogant Lord Governor and restore the land's precious balance. Despite their combined power, Audin has a secret weapon. Built by Ilsa Wright, the greatest magical engineer since Lord Colt himself, the Mark V magical armor is a nearly unstoppable force on the battlefield. But will it be enough to turn the tide and save Audin? The people better hope so, because there's no mercy for those that upset the balance.
