Viking Iceland. The year 1000. Civil war looms as pagans and Christians struggle for mastery in the all-island legislature. Zealous King Olaf of Norway embargoes trade and threatens forcible conversion if Icelanders will not convert themselves. In his adventurous youth Kári Sigurdsson won fame, wealth and the nickname Kári the Warrior fighting for King Olaf in two invasions of England. Now a prosperous farmer in his native Iceland, he thinks he has killed enough. But he is embroiled in a vicious feud over an inheritance. With the aid of a young lawyer - his foster-brother - his chieftain's crippled daughter and a half-Irish slave-girl, both of whom love him, and a mysterious Welsh trader who is interested in more than trade, he tries to resolve his problems through Iceland's elaborate court system, but is thwarted at every turn by the treachery of his ambitious wife, the jealousy of his chieftain and the unremitting enmity of his adversary, all pagans. Inclining towards the Christians but bound by pagan ideas of honor, Kári is forced into a revenge killing that can only lead to outlawry and death - unless his allies can find a way out.
