Shark Drunk is, in part, the tale of two men in a very small boat on the trail of a very big fish. It is also a story of obsession, enchantment and adventure. A love song to the sea, in all its mystery, hardship, wonder and life-giving majesty.

In the great depths surrounding the remote Lofoten islands in Norway lives the Greenland shark. Twenty-six feet in length and weighing more than a tonne, it can live for 200 years. Its fluorescent green, parasite-covered eyes are said to hypnotise its prey, and its meat is so riddled with poison that, when consumed, it sends people into a hallucinatory trance.

Armed with little more than their wits and a tiny rubber boat, Morten Strøksnes and his friend Hugo set out in pursuit of this enigmatic creature. Together, they tackle existential questions, experience the best and worst nature can throw at them, and explore the astonishing life teeming at the ocean’s depths.
