27:13: To the Power Against, by Carrie Smith and Stephanie Lantry (2012 trade paperback)

Catalina Jones--a probabilistic risk assessor--finds herself in improbable situations after an unlikely accident involving a microwavable burrito and a graviton missile. To combat the chaos she creates everywhere she goes, she develops an intervention system using complex mathematic equations. It's a great indie comic, where the female protagonist depends on brains rather than beauty, with amusing plot twists, fun science, and threatening men in black suits thrown in.
