The country is in turmoil. With the capital city occupied, half a million refugees are on the march, looking for safety on the frontier, accompanied by Lady Flint's soldiers. But escaping war is never easy, and soon the battle may find them, whether they are prepared or not.

Back in the capital, Michel Bravis smuggles even more refugees out of the city. But internal forces are working against him. With enemies on all sides, Michael may be forced to find help with the very occupiers he's trying to undermine.

Meanwhile, Ben Styke is building his own army. He and his mad lancers are gathering every able body they can find and searching for an ancient artifact that may have the power to turn the tides of war in their favor. But what they find may not be what they're looking for.

The war with the Eastern Empire ended in stalemate some eighty years ago, thanks to Nall's 'Engine', a wizard-crafted weapon so powerful even the Deep Kings feared it. The strike of the Engine created the Misery - a wasteland full of ghosts and corrupted magic that now forms a No Mans Land along the frontier. But when Galharrow investigates a frontier fortress, he discovers complacency bordering on treason: then the walls are stormed, and the Engine fails to launch. Galharrow only escapes because of the preternatural magical power of the noblewoman he was supposed to be protecting. Together, they race to the capital to unmask the traitors and restore the republic's defences. Far across the Misery a vast army is on the move, as the Empire prepares to call the republic's bluff.
