The Sunday Times bestseller. When racing 435 miles through the jungles and mountains of South America, the last thing you need is a stray dog following you. That’s exactly what happened to Mikael Lindnord, the captain of a Swedish adventure racing team, when he tossed a meatball to a scruffy but dignified mixed breed one afternoon. When they set off the next day, the dog followed them. No matter how hard they tried, they couldn’t shake him off – and soon Mikael realized he didn’t want to. Crossing rivers, battling illnesses and injuries, and pushing through some of the toughest terrains on the planet, the team and the dog made their way to the finish line, where Mikael decided to rescue Arthur and bring him back to his family in Sweden, no matter the cost. Reactions to Arthur’s story: “An incredible journey” - Daily Telegraph.
