The black guard - A. J. Smith

The Duke of Canarn is dead, executed by the King's decree. The city lies in chaos, its people starving, sickening, and tyrannized by the ongoing presence of the King's mercenary army. But still hope remains: the Duke's children, the Lord Bromvy and Lady Bronwyn, have escaped their father's fate. Separated by enemy territory, hunted by the warrior clerics of the One God, Bromvy undertakes to win back the city with the help of the secretive outcasts of the Darkwald forest, the Dokkalfar. The Lady Bronwyn makes for the sanctuary of the Grass Sea and the warriors of Ranen with the mass of the King's forces at her heels. And in the mountainous region of Fjorlan, the High Thain Algenon Teardrop launches his Dragon Fleet against the Red Army. Brother wars against brother in this, the epic first volume of the long war.
