Marked by the Serpent's Brand and exiled, Kael infiltrates House Velcrain as a fake son-in-law to break his curse. He discovers the Covenant intends to sacrifice seven noble bloodlines to resurrect an ancient serpent god.
Seraphine, whose blood magic suppresses his curse, becomes his ally. At the Serpent's Grave, Kael unleashes his serpent-human hybrid form to stop the ritual, betting his humanity and the world’s fate on one blow.
Will the battle free him, or make him the god’s vessel?
