T.A. Pratt

T.A. Pratt's Marla Mason series began with novel Blood Engines in 2007, and continued with Poison Sleep, Dead Reign, Spell Games, Broken Mirrors, short prequel novel Bone Shop, and numerous short stories, of which "Shark's Teeth" is the latest. (No prior knowledge of the series is necessary, however; all you need to know is that Marla is a sorcerer who enjoys punching people, and that should be abundantly clear from the text.)
