In the cold north, House Valmont has guarded Frostvale for generations. Its name is respected. Its secrets are not meant to be spoken. Now, trouble has come to Valmont all at once. The Viscount is ill with a sickness no doctor can explain. His eldest son has vanished without a trace. So the family calls on the second son, the one who left. Arden Valmont walked away from his name at fifteen and built a quiet life under another. He never wanted a title, a house, or a mission. But when a letter reaches him, he comes home anyway. He just doesn’t know yet how much the shadows have been waiting for him.
