Two of Swords (The Two of Swords, 1)

"Why are we fighting this war? Because evil must be resisted, and sooner or later there comes a time when men of principle have to make a stand. But at this stage in the proceedings," he added, with a slightly lopsided grin, "mostly from force of habit."A soldier with a gift for archery. A woman who kills without care. Two brothers, both unbeatable generals, now fighting for opposing armies. No one in the vast and once glorious United Empire remains untouched by the rift between East and West, and the war has been fought for as long as anyone can remember. Some still survive who know how it was started, but no one knows how it will end. Except, perhaps, the Two of Swords.
World Fantasy Award-winning author K. J. Parker delivers the first volume of his most ambitious work yet-the story of a war on a grand scale, told through the eyes of soldiers, politicians, victims, and heroes.
