It's her first case and it might be her last. Soriya has worked her entire life to become the Greystone-protector of her city, Portents, against the growing shadows of myth and legend. All her efforts are in jeopardy when she is struck down by the destructive power of the Minotaur. Soriya must now find a new path. Only one thing is certain-she's going to need help. Beth, a researcher with insight into the city, has been locked in her own mystery-hunting for the recently stolen hammer of Hephaestus. Working together to unravel the secrets hidden in Portents, Soriya and Beth must learn to trust the other's unique perspective. However, they aren't the only ones seeking answers as the Minotaur turns his rage on the city… starting with Soriya's beloved teacher. The secrets of Soriya's training are revealed in the first adventure of this new Greystone trilogy.
