Photographs, maps, and drawings combine with detail-rich texts to introduce notable land and air explorers and the stories of their adventures. Pipe briefly glosses over eleven journeys of worldwide exploration, beginning with Marco Polo and ending with late-twentieth-century explorers (e.g., "daredevil explorer Steve Fossett" and his around-the-world balloon attempt). Archival photographs, sidebars, and multiple fact-filled features (sidebars, text boxes, etc.) combine with accessible texts to present a thorough (albeit busy) introduction to the history and current enterprise of spies and spying. Luminous watercolor with pen and pencil illustrations capture the icy Arctic winters, the tundra's fleeting midsummer verdancy, and the migrating groups' gracefulness. In this Choose-YourOwn- Adventure-style book, readers select a persona - "early Antarctic explorer" (with Amundsen or Scott), "modern-day adventurer," or modern-day worker - and make decisions at narrative crossroad points.
