The ninth book in the bestselling series tells the story of
John Wesley Powell, the one-armed geologist who explored the Grand
Canyon


John Wesley Powell (1834–1902) always had the
spirit of adventure in him. As a young man, he traveled all over the
United States exploring. When the Civil War began, Powell went to fight
for the Union, and even after he lost most of his right arm, he
continued to fight until the war was over. He then embarked on the 1869
Powell Geographic Expedition, which became the first official US
government-sponsored passage through the Grand Canyon. Over the course
of three months, the explorers lost their boats and supplies, nearly
drowned, and were in peril on multiple occasions. However, they made it
through, and Powell would come to be known as one of the most epic
explorers in history! Equal parts gruesome and hilarious, this latest
installment in the bestselling series takes readers on an action-packed
adventure through American history.
