Edward Curtis was thirty-two years old in 1900 when he gave it all up to pursue his great idea: He would try to capture on film the Native American nation before it disappeared. At once an incredible adventure narrative and a penetrating biographical portrait, Egan's book tells the remarkable untold story behind Curtis's iconic photographs, following him throughout Indian country from desert to rainforest as he struggled to document the stories and rituals of more than eighty tribes. Even with the backing of Theodore Roosevelt and J.P. Morgan, it took tremendous perseverance--six years alone to convince the Hopi to allow him into their Snake Dance ceremony. The undertaking changed him profoundly, from detached observer to outraged advocate.
