From the publisher's website:
In the frozen depths of winter, murderous winds mercilessly batter the crumbling Priory of Cymer. Within, trapped by their duty and the heaped snowdrifts that render travel near impossible, the few remaining faithful huddle together and tend the sacred places of their forbears. With the weather worsening, nerves fray and tempers snap as the wind howls its mournful dirge for the forgotten dead of a fallen time. But the worst is yet to come. One of those trapped within holds a murderous grudge that only blood can expunge and as the storm reaches its savage height terrible revenge is wrought amid the frigid halls and faded glories of a bygone age.
This expanded, reorganised edition of Retribution features new art and new text.
