When the salmon runs of the Pacific Northwest began to decline, Guido Rahr was one of the few who understood why. As dams, industry, and climate change degraded the homes of these magnificent fish, Rahr saw that the salmon of the Pacific Rim were destined to go the way of their Atlantic brethren: near extinction. Telling an inspiring story, Tucker Malarkey follows Rahr as he contends with scientists, Russian oligarchs, corrupt officials, and unexpected allies to save an animal whose future is closely linked to our own.
