The Sunshine Silver Mine in Wallace, Idaho was a hard rock mine that should never have burned. But it did, in 1972, and ninety-one miners died. The cause of the fire was never fully determined. Now, nearly half a century later, a political race, mysterious artifacts, and a murder reopen those old wounds for the citizens of Wallace. Cody Marsh, who had only hoped to find a connection to her past, will find herself in the center of a deadly game of atonement and retribution.
