Millions of readers of Hatchet, The River, Brian's Winter, and Brian's Return know that Brian Robeson is at home in the Canadian wilderness. He has stood up to the challenge of surviving alone in the woods. He prefers being on his own in the natural world to civilization. This story takes place two years after Brian had been stranded in the Canadian wilderness. When Brian finds a dog one night, a dog that is wounded and whimpering, he senses danger. The dog is badly hurt, and as Brian cares for it, he worries about his Cree friends who live north of his camp. His instincts tell him to head north, quickly. With his new companion at his side, and with a terrible, growing sense of unease, he sets out to learn what happened. He sets out on the hunt. The tale of adventure proceeds as Brian and his dog find what happened when a murdering bear has gone wild.
