The Archmage rules the island of wizards and has banned the use of magecraft in warfare, but there are corsairs raiding the Caladhrian Coast, enslaving villagers and devastating trade. Barons and merchants beg for magical aid, but all help has been refused so far. Lady Zurenne's husband has been murdered by the corsairs. Now a man she doesn't even know stands as guardian over her and her daughters. Corrain, former captain and now slave, knows that the man is a rogue wizard, illegally selling his skills to the corsairs. If Corrain can escape, he'll see justice done. Unless the Archmage's magewoman, Jilseth, can catch the renegade first, before his disobedience is revealed and the scandal shatters the ruler's hold on power.
