Freya has always craved--and feared--adventure. Traipsing all over the world is simply not what dignified rockhopper penguins do. But when she hears about Captain Salomon August Andree's hot-air balloon expedition to the North Pole, Freya packs her copy of Hints to Lady Travellers and hops on board. Only moments after leaving land, Freya discovers a fellow stowaway! Meet Zoose, the scrappy, uncouth mouse whose endless wisecracks and despicable manners make him a less-than-ideal travel companion. When the hot-air balloon is forced to land in the Arctic, these polar opposites must learn how to get along. Their very survival depends on it. Debut author Emily Butler spins wonder and whimsy and Jennifer Thermes contributes over fifty black-and-white illustrations to bring this enchanting friendship tale to life.
