'Ella and her brother Emery are alone in a city that's starving to death. If they are going to survive, they must get away, upcountry, to find Emery's mum. But how can two kids travel such big distances across a dry, barren and dangerous landscape? Well, when you've got a few big doggos, the answer is you go mushing. When Emery is injured, Ella finds herself suddenly responsible for safely navigating the wheeled dog-sled through rough terrain, and even rougher encounters with desperate people.'
