Picked this 1935 book up after seeing the 1940 movie of the same name, starring Jean Arthur and William Holden. I didn't realize that the movie was just a snippet of the story, which not only covers hauling precious freight through hostile territory, but also surviving in the harsh desert, fighting a guerrilla war that no one wins, and building a home in a lawless territory.
Phoebe Titus was en route to California when her father's illness forced a permanent stop in Tuscon. To survive (eventually on her own), Phoebe bakes pies; later she invested her pie money and uses their wagon to earn more money. She discovers she has an entrepreneurial spirit, and is able to build on her nest egg, and even plan ahead - predicting successfully that the the local fort will be emptied to support the Northern Armies in the Civil War. She's a straight shooter, and a good business partner; she's not as facile, though, at dealing with underhanded men, or men who are interested in her personally.
It's a strikingly good story about an independent-minded woman in the west. You don't run into many westerns from this time period that put a woman in the starring role, and the author's surprisingly sympathetic rendering of Cochise and Mangas Coloradas is downright groundbreaking. I did find Phoebe's "uneducated dialect" as created by the author (which oddly vanished when she spoke to Native Americans or Mexicans) tiresome (seriously, how often can she "git a go'in' "? I pity the typesetter), but ultimately forgivable. Good tale, ahead of its time.
