Two friends sail together. Their plan is to catch a Greenland shark. They sail a rubber dinghy, well-equipped with chains and wire and a rotten cow's head as bait.

They are happy, and they are on a hunt for the impossible.

While they wait - often and long in all seasons of the year - they tell each other stories about Greenland sharks, examine the life in the ocean, ponder on things great and small, discuss marine research, heroes in science, poets, artists, the endless star-speckled heavens and the ocean floor beneath us - the origin of everything.

But most of all, the Greenland shark.

The living fossil, which can live to be several hundred years old, can weigh a ton, has eyes full of parasites that makes them glow green in the deep dark, whose flesh is so poisonous that eating it will make you very drunk, shark drunk. 

HAVBÓKIN (Shark Drunk, English title) has been praised as the best Norwegian non-fiction novel
