This book tells the extraordinary story of the life, trials and explorations of Father Jacques Marquette in North America. The reader learns not only of his life as an explorer of the North and of the Mississippi River, but as a beloved peacemaker amongst the Native Americans of the region. The story unfolds as a young boy named Davey is enjoying his family vacation in Northern Michigan. Davey is fascinated by the tales his Grandfather, Arnie, tells around the campfire on the cool Michigan evenings. He hears the stories of Native American lore and the brave explorers of the region. In particular, he hears the stories of Father Jacques Marquette and his involvement with establishing the historic Jesuit Missions of Michigan and the extreme bravery and dedication of the “black robes.” Davey learns of Father Marquette’s most famous achievement---the mapping and exploring of the upper Mississippi River. During the many evenings of storytelling, Davey also learns the enthralling legend of Louis the squirrel, and how the squirrels of Michigan became black.
