Death descends upon the Ice Plains. Rory and Ingefær investigate the mysterious murders of an entire village on the Ice Plains...as winter approaches. Bones are found stripped of all sinew; other dead bodies show no sign of injury at all. How were they killed? Their search finds a pack of dead waergs clawed to death. And days later, they spot a double loop of snakes carved into a pine tree. Just what the Hel is going on? How much blood will be spilled to unravel the mystery? How much of it will be their own?
