Sannarah lives from one deadline to the next. As a Wrath Demon, she is obliged to provide a certain number of human souls to the Fallen God every month. One day she follows the shady tip-off and finds herself in the middle of a gruesome crime scene as the main suspect.
Melkyal, an Archangel of Justice, gives her a choice: she can help him find an actual perpetrator and get a clean slate, or refuse and spend a few weeks in jail for petty crimes. With looming deadlines, she can't afford to refuse.
