In August 2023 I took a 10-day photography trip to the west of Hudson Bay, in the state of Manitoba in the center of Canada. My goal was to enter the inaccessible kingdom of the polar bear, live for a few days the experience of being surrounded by oceans of tundra and boreal forests, and ultimately photograph the largest terrestrial predator on the planet. In this book I try to summarize the most notable aspects of that trip and accompany it with the photographs I was able to take of both the wild animals and their surroundings.
