Mercy Harding isn't entirely human. Turns out, she's not the only one harboring a monstrous side. As a brash young monster hunter, Jonah faced a terrifying creature known as the Final Visitor. He barely escaped with his life and now shares the Visitor's devastating power. But if he dares to use it, he brings the monster closer. With the Final Visitor on Jonah's trail and time running short to free Mercy from her wolfish possession, the two continue their journey to Port Falrest. Hoping to pick up speed, they catch a ride from a troop of traveling musicians. But can Mercy keep her wolf side hidden among these strangers? Especially when a particularly nosy one keeps grilling her about her true feelings for Jonah?
