American meteor

Summary: In this ... tale of Manifest Destiny, Stephen Moran comes of age with the young country that he crosses on the Union Pacific, just as the railroad unites the continent. Propelled westward from his Brooklyn neighborhood and the killing fields of the Civil War to the Battle of Little Big Horn, he befriends Walt Whitman, becomes a bugler on President Lincoln's funeral train, apprentices with frontier photographer William Henry Jackson, and stalks General George Custer. When he comes face-to-face with Crazy Horse, his life will be spared but his dreams haunted for the rest of his days.
