The book opens with Leaf Fielding's arrest in a pre-dawn police raid and ends five years later with his release from jail.The narrative moves back and forth between the harsh world of prison and his previous life - from a childhood at a brutal boarding school onto undergraduate days and his LSD epiphany in the summer of love, 1967.Acid transformed him in an instant from nerdy scholar to footloose freak. His ten years of adventures in the hippie underground gave the title to this book - a quote from a Bob Dylan song - they also took him across Europe, to the Andes, to Indochina and on to the edge of the known universe. They also led inexorably to his downfall.

    Mackinnon quits his job in Australia, he knows only that he longs to travel to the Well at the World’s End, a mysterious pool on a remote Scottish island whose waters, legend has it, hold the secret to eternal youth.Determined not to fly (‘It would feel like cheating’), he sets out with a rucksack, some fireworks and a map of the world and trusts chance to take care of the rest. By land and by sea, by train, truck, horse and yacht, he makes his way across the globe – and through a series of hilarious adventures. He survives a bus crash in Australia, marries a princess in Laos, is attacked by Komodo dragons and does time in a Chinese jail. The next lift – or the next near-miss – is always just a happy accident away.This is the astonishing true story of a remarkable voyage, an old-fashioned quest by a modern-day adventurer.
