Gr 5-9-All of Walker's impressive writing talents are on display in this book on the frozen continent. The author's clear and lively narrative begins with a brief history of the first explorers, including some grisly deaths, and then describes in detail the work of current researchers. Walker paints a vivid picture of the hardships and special considerations required of those who work in Antarctica. Children will almost shiver as they read the description of the scuba diver's preparations to enter an icy lake. Additionally, the author does a great job of explaining some really complex scientific activities, such as mapping the ground using ice-penetrating radar, so that readers without great knowledge of advanced science can grasp how this work is done. She also shows how Antarctic research can help them understand global climate change and other types of earth-science research. Nearly every page has sharp color photos of the continent and researchers in action or explanatory diagrams. With its superb design and Walker's gripping prose, this book will draw readers in and keep them involved.-Denise Schmidt, San Francisco Public Library
