In this historical adventure for middle grade readers, a dog travels through time and rescues a family in New Orleans during Hurricane Katrina. Ranger, the time-traveling golden retriever with search-and-rescue training, arrives in New Orleans as Hurricane Katrina approaches and residents start to evacuate the city. Ranger meets Clare Porter, who is searching for her grandmother. Once Ranger helps Clare find Nana, he takes shelter with them at their home in the Lower Ninth Ward, and they wait for Clare's father to return from the gas station. But there's no sign of him as hours pass and the weather gets worse. The wind picks up and rain pours down. And when the levees break, floodwaters dangerously rise, and Clare and Nana are separated. Can Ranger help Clare navigate the flooded streets to safety and back to her family? 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
