Driven by the ghosts of the Darakyon, Achaeos has tracked the stolen Shadow Box to the marsh-town of Jerez, but he has only days before the magical box is lost to him forever. Meanwhile, the forces of the Empire are mustering over winter for their great offensive, gathering their soldiers and perfecting their new weapons. Stenwold and his followers have only a short time to gather what allies they can before the Wasp armies march again, conquering everything in their path. If they cannot throw back the Wasps this spring then the imperial black-and-gold flag will fly over every city in the Lowlands before the year's end. In Jerez begins a fierce struggle over the Shadow Box, as lake creatures, secret police and renegade magicians compete to take possession.
