'You can run, but you will never be free.' Half a year after the events of Heart Of Dust, Doran Ó Seanáin now finds himself trapped between two worlds while belonging to neither. Held in contempt by the upper class for the turmoil he caused during Archon Bryson's reign and resented by the miners for selling out, Leonora Darkwater's bid to purchase the mines from the crown may be his salvation. But the offer is far more complicated than it appears, and the only person Doran trusts is the same man who threw his life into chaos. Haunted by his past, held hostage by his debt to the Archon, and a slave to the poison that keeps him alive, atonement feels perpetually out of reach for Nathaniel Morgenstern. Too much damage has been done and too much has gone unsaid for time alone to heal the wounds between him and Doran. Unfortunately, time is the one thing they don't have as their lives collide once more. There are vipers in Arajon; the mines aren't finished with Doran, and the sand in Nathaniel's hourglass is running out.
