Focusing on the bold and courageous explorers and determined settlers who extended the frontier to the western coastline, author Sherry Garland narrates in the voices of figures from history. She personalizes the adventures of Sacagawea, Jedediah Smith, George Catlin, and Annie Oakley. She furthers the timeline with characters representing whole populations, including a girl traveling west in a prairie schooner, a Santa Fe merchant, a gold prospector, a Pony Express rider, a Chinese railroad worker, a young boy barreling across the Great Plains in a steam locomotive, and a vaquero. Talented artist Julie Dupr Buckner carefully researched the historical details for her evocative illustrations. Each image furthers the storyline and reinforces the emotional connection to the chronicle. Together, the narrative and the art tell the tale of ancestors who created the foundation of the American nation.
