Twin Rivers is a snow-covered town cut off from the rest of the world, where police officer Tanu Larsson was sent for seasonal work.Not far from the city, on a mountain range, wild animals tore to pieces two young biologists. Tana and pilot Cameron, whom she cannot stand, are forced to go to the scene of the tragedy. They see a terrible sight. The killings are more like a bloody ritual, and the ridge itself has a bad reputation, where torn bodies have already been found. Soon strange things begin to happen around Tana, and Cameron is the prime suspect. All the fault of suspiciousness and personal hostility? Or is Tana closer to a clue?Then she should beware, because this is not the last blood hunt for Twin Rivers.
