Marking the 100th anniversary of World War I, this series takes a detailed look at the course of events in the Great War and the conflict's lasting impact on the world. The different periods of the war are divided into their own titles, as are the key combat roles of Canada and the United States. Readers will learn about the political and social turmoil of the time, important battles throughout the war, the horrific conditions of trench warfare, the gripping accounts of naval and submarine combat, and the hero worship of flying aces. Documents, artifacts, and first-hand accounts help young readers relate to the subject. Sidebars, short biographies, fact boxes, timelines, and stimulating text-dependent questions will keep readers engaged and motivated.
