Reviews

"[A] handsome tribute to Clark's near-lifelong companion and slave. Carefully noting where details are scant or absent, he traces York's early years, significant role in the expedition that is 'still considered the greatest in United States history,' and later and later unhappy experiences. . . . Rich in eye-opening observations." —Kirkus Reviews

"Pringle tells the story well." —School Library Journal
