They say you can't go back home, but Marin Sinclair, end-of-life doula, doesn't expect her life to be in danger when she answers a mysterious plea for help from a long-ago friend and returns to Dinetah, the Navajo Nation. Her past there holds memories she is reluctant to confront, but what about her life then would make someone want to kill her? Navajo Nation Police Sergeant Justin Blue Eyes shares a connection with Marin from the past, and he has a few questions of his own when Marin disappears—such as why the Nuclear Regulatory Commission has agents investigating the abandoned uranium mines on the reservation and how Marin is connected. Marin needs to survive to find any answers, and to do so she is forced to run, going off the grid on her own in the Lukachukai mountains with unknown killers close behind.
