In Helvik, a single rule governs the people: ‘No person of Helvik may kill another person of Helvik. Any person who breaks this rule is no longer a person of Helvik.’

Gunnarr remembers a time before the rule, when blood feuds and petty rivalries led to endless death. In the days since, an uneasy peace has fallen over the town, and Gunnarr has made himself the man to enforce it.
