Where does the sun continually shine, even at night? How do penguins keep their eggs warm? How can there be deserts in the coldest places on Earth? This title unlocks the mysteries of the Arctic and Antarctic regions. It looks at expeditions to the North and South Poles--from the earliest adventurers to modern tourist cruise--and investigates how people and animals survive on these frozen frontiers.
