Yet among the dangers lies one of the most beautiful and fragile ecosystems in the world. By 1928, dozens of expeditions had scoured the Himalayas in search of the panda bear, an animal many believed to be a myth. That year the two eldest sons of President Theodore Roosevelt and a small team of scientists and naturalists launched their own dangerous journey. Lost in blizzards, attacked by robbers, ravaged by illness, and cut off from food supplies, the brothers' crew was pushed to its physical and emotional limits. They would accomplish what years of exploration had not-introducing the panda to the Western world. Along the way, they documented a rapidly disappearing landscape and helped bring about a new era of conservation biology. In The Beast in the Clouds, Nathalia Holt brings these events to life in a gripping nonfiction thriller about ambition, survival, and the indomitable Roosevelt spirit.
