The Smallest Day by J.M. Redmann

One person dead, another the target. Micky Knight is tasked with protecting Rabbi Sarah Jacobson, from New York, who is hiding in the city she hates, New Orleans. Unsure if Sarah was targeted by one lone killer or a sophisticated hate group, Micky is on edge and uncertain of how to guard her. Or if she can. Sarah is on the verge of a breakdown, from witnessing someone she loved being murdered, to being a stranger in a place she never wanted to see again. Micky reluctantly takes another case from an old high school acquaintance to find her young boytoy who stole important business secrets. The case is messy, likely illegal, and throws Micky into a past she thought she had left behind. Both cases lead her to unexpected--and dangerous--places.
