In a kingdom where Sun-Iron is used to purge the supernatural, being a werewolf is a death sentence. For Kaelen, the full moon brings no power, only a "Silver Fever" that threatens to tear his body apart from the inside out. He is a Seeker, an outcast who must hide his identity or face execution by the fanatical Sentinels of the Pure Blood. Driven by a fading map and a desperate hope, Kaelen journeys toward the Valley of the Silent Monks. His goal is the Stilled Waters, a legendary sanctuary said to have the power to freeze time and silence the beast forever. But the path is blocked by enchanted gates and hunters who can smell the rot in his blood from miles away. Everything changes when Kaelen is rescued by Elara, a mysterious hunter with her own reasons for hating the Order. She offers him a bargain: she will guide him to the cure, but only if he uses his cursed strength to help her stop a rising darkness. As the lunar cycle nears its peak, Kaelen faces a brutal choice. He can destroy the monster within and lose the power he needs to survive, or he can embrace the beast and become the very nightmare the world wants to burn. One map. One cure. One night to decide the fate of the reach.
