Chilling Effect — Melissa F. Miller

Investigating an embezzlement scheme at a Native American casino tears federal prosecutor Aroostine Higgins away from a romantic getaway with her husband, Joe. Dispatched by her superior in the hopes that her Native American roots will win trust in a community wary of outsiders, Aroostine goes on high alert when she finds her would-be informant executed in his home.

Money skimming, murder, and rumors of stolen military weapons are linked to someone on the reservation, and Aroostine butts heads with tribal authorities bent on solving the crime and doling out punishment on their own terms. After narrowly escaping a deadly ambush, she and Joe must somehow protect each other and another whistle-blower from a killer's bullet. She'll have to connect with the heritage she left behind in order to track down this ruthless killer.
