USA Today bestseller Melissa F. Miller's Aroostine Higgins series continues with a case that requires the federal prosecutor to connect with her heritage in order to stop a remorseless killer.

Rumors of money skimming, murder, and stolen military weapons swirl around a Central Oregon reservation. Aroostine is sent to investigate in the hopes that her Native American roots will help her win trust in a community wary of outsiders.

She arrives to find her would-be informant executed in his home. As Aroostine digs deeper into rumors and the murder, she butts heads with tribal authorities bent on solving the crime and doling out punishment on their own terms. After Aroostine and her husband Joe narrowly escape a deadly ambush on the reservation, she's not sure who she can trust ... and who's trying to kill her.
