Gr 4-6--Each book begins with an exciting account of a medal-winning race at a recent Winter X Games or Winter Olympics. Ensuing chapters cover the history of the featured activity and how it has evolved into top level, international competition. The well-chosen photos are eye-catching action shots, such as images of skiers doing back flips or snowmobile riders going airborne. Most of these sports can be dangerous, and the volumes mention stars such as ski superpipe athlete Sarah Burke, who died in 2012 as a result of a fall during a practice run. Overall, this set uses a positive tone and conveys enthusiasm for these athletics, emphasizing that readers can practice them while keeping as safe as possible. Thumbnail sketches of innovators and youthful superstars will keep young readers engaged.[Page 53]. (c) Copyright 2013. Library Journals LLC, a wholly owned subsidiary of Media Source, Inc.
