The Black Wing's Wrath

From publisher blurb:

Hope is lost. The Knightlord and his monstrous mount cast a long shadow across the city. The creature looses a guttural shriek that echoes through the bloodstained avenues. Howls of despair echo from the city below as civilian and warrior alike peer upwards from every corner of the siege. Will our heroes be able to pluck victory from its slavering maw, or will all their sacrifice have been for nothing? Find out in SF 012, The Black Wing's Wrath.
