Legionnaire is a gritty High Fantasy series set on the borders of the far-flung Republic of Aquila. While political in-fighting and scheming are the order of the day in the heart of the Republic, the borderlands are awash with dangers only kept in check by the might of the legions. Fell magics, savage peoples, and scheming empires all threaten the country Patrician Marcus Venandus has sworn to defend using his wits, military strategy and his small command of highly disciplined legionnaires.

If folks had any business living in the small Colorado town of Hadrian’s Well, there wouldn’t be places like Dead Man’s Field and Widow’s Creek surrounding it. There’s just something different about the territory—something that draw all sorts of preternatural creatures towards it. If long term residents know what that something is, they aren’t talking, but newcomer Deputy Sheriff Joanna Dawson may just have what it takes to figure it out—if she survives long enough.
