A vivid yet even-handed account of the ill-fated Donner Party—the California-bound wagon train that was forced by impassable snow to camp for the winter of 1846—47 on the eastern slopes of the Sierra Nevada, resorting to cannibalism when there was literally nothing else to eat. Calabro neither shrinks from nor sensationalizes this aspect of the story. Instead she places it in a carefully constructed context beginning with the start of the journey in Springfield, Illinois, on April 15, and chronicling each unfortunate decision along the way that ultimately led to the company’s entrapment. Making good use of primary sources, especially the letters and memoirs of Virginia Reed, who turned 13 on the journey, the author tells of Virginia’s excitement at having her own pony to ride west. However, she doesn’t limit the story to Virginia’s perspective, but skillfully profiles many members of the party, including Virginia’s dynamic father, James, who strongly favored taking an unproven shortcut, and the intelligent and perceptive Tamsen Donner, who was firmly against it. The result is a combination of well-researched factual detail, a gripping narrative, strong characterizations, and a thoughtful analysis of the historical record.
