Ursun's Teeth — Graham McNeill

RETIRED GENERAL KASPAR von Velten returns to the frozen city of Kislev to continue his duties as the Emperor's ambassador to the court of Tsarina Katarin. With the massed hordes of Chaos marching towards the strategic rock formation known as Ursun's Teeth, the combined armies of the Empire and Kislev must ride out to meet them in battle. But with the outbreak of plague and a string of assassinations, it becomes clear that a Chaos agent is operating within the city and Kaspar must foil them before they bring the defences tumbling down.
