Shadows Linger by Glen Cook

The excerpts introduce the Black Company, a mercenary unit serving a powerful sorceress known as the Lady, as they pursue Rebel enemies and search for a former comrade, Raven. The narrative focuses on the perspective of Croaker, the Company's physician and annalist, who chronicles their dangerous mission in the northern city of Juniper and its surrounding areas, including a mysterious, malevolent black castle. A significant subplot details the struggles of Marron Shed, a tavern owner in Juniper, who becomes entangled with both the local criminal elements and the Black Company's pursuit of Raven, ultimately finding a hidden sense of courage. The overarching threat involves the potential resurrection of the Dominator, the Lady's ancient enemy, whose influence is tied to the black castle and the fate of the White Rose, who is revealed to be the young girl Darling.
