“A treat for middle-graders of an ecological bent.” — Bulletin of the Center for Children’s Books (starred review) At the top of our world is a huge wild place called the Arctic. In the winter, it is a cold and barren land, where few animals can survive. But when spring comes, it attracts animals from every corner of the earth. This lushly illustrated picture book celebrates the resilient wildlife and barren, beautiful landscapes of the Arctic Circle, tracing the awe-inspiring spring migration of millions of creatures to the Arctic and reminding the reader of the hardships and harmony of life in the wild. Back matter includes additional information about the arctic, a glossary, and an index.
