In this middle grade historical adventure, a dog travels through time to take part in a voyage from New Zealand to the South Pole. Ranger, the time-traveling golden retriever with search-and-rescue training, joins an early twentieth-century expedition journeying from New Zealand to Antarctica. He befriends Jack Nin, the stowaway turned cabin boy of Captain Robert Falcon Scott's ship. They're racing against a rival explorer to reach the South Pole, but with unstable ice, killer whales, and raging blizzards, the journey turns into a race against time . . . and a struggle to stay alive. Praise for the first book in the Ranger in Time series: "This excellent story contains historical details, full-page illustrations, and enough action to keep even reluctant readers engaged." —School Library Journal "The third-person narration expertly balances Ranger's thoughts between the appropriately doglike (squirrels! bacon!) and the heroic (Ranger's drive to find and protect)." —Kirkus Reviews "McMorris's richly rendered illustrations heighten the plot's many moments of danger and drama, and Messner incorporates a wealth of historical details into her rousing adventure story." —Publishers Weekly
