Traitor's Blade

Traitor's Blade(Greatcoats book 1) features a trio of swashbuckling swordsmen in the vein of The Three Musketeers. Like The Gentleman's Bastards books, the setting is somewhat dark, and bad things happen but the humorous banter between the protagonists keep the story fun rather than depressing. The plot moves quickly, but the first person viewpoint means the focus is on why the characters do what they do. The ramifications of their actions are explored in the sequels.
