In Whistler, British Columbia, dogs can be found riding chairlifts, perched on skiers' shoulders, and even descending from helicopters--all in the race to the scene of an avalanche and the race against time to save people who were caught in the path of destruction. Meet Henry, a lovable border collie who is slight but strong, and the team of dogs and human partners he works with in the beautiful and sometimes dangerous mountains. Through the action-packed primary text, informative and engaging interstitials that delve into the history and science behind avalanches and rescue dogs, and eight pages of stunning full-color photographs, young readers will experience real-life rescues and gain a new appreciation for the bond between dogs and humans.
