The title story is much more consciously literary than the other stories in this short collection. It's a tale of broken oaths, murder, revenge, legal drama and redemption in medieval Iceland.
Several of the other stories have similar themes but have a somewhat different tone, being more like a cross between a short biography of an individual and the anecdotes about him that would get told down the pub on a long winter's night.
The latter-most stories take a wider look at the Norse world as they tell of Icelanders who travel abroad. One character goes so far as Rome, escaping the North altogether for a while.
Both types offer a fascinating glimpse of the prevailing culture in an entertaining fashion.
