Writing from the point of view in the early 80's and fresh from the chaos of the 70's oil crisis Batchelor naturally used this experience to build his world which in SF terms would be classified as a "near future" narrative.
More accurately his book is that rare animal in the XX century a political fiction talking about the issues of freedom and personal responsibility in the face of antiutopian fictions like 1984 or The Brave New World and actual political utopian projects like the Soviet Union or Third Reich.
It is easily recognizable that Batchelor is writing from a Libertarian perspective and that would allow me to label the book as a 'Libertarian fable' however this book is much more.
Taking Sweden in the early 70's as the location of his books beginning the writer appropriates the heritage of Norse mythology and epic poems for his flawed hero and this imagery stays with the reader throughout the book in tone, names and a whole chapter that takes place during a 'berserk' war fury during which the Hero Skallagrim Strider commits many crimes.
However Batchelor posits his crimes against the political crimes of those who convicted not just the hero but millions to a fate worse than his. The metaphor of the 'road to hell is paved with good intentions' is aptly used here.
In the end the Hero is given a sort of a political redemption by becoming a "Republic of one" incarnating the libertarian ideal of personal responsibility and freedom in the wastes of Antarctic islands.
Fascinating read that will stay with you, slightly dated due to the basic premise of a breakdown in world social order by Oil crisis, racism and religious fervour. Otherwise, to the point, asking the most fundamental questions about the political animal-Man.
