Meet the first feminists of the frontier: the fearless, formidable Petticoat Party wagon train! Spunky twelve-year-old Phoebe, her sister Amelia, the alluring Kennan twins, and the rest of the ladies are ready to hit the trail and take on hardship and hunger - even lovesick Indians - with aplomb. The Wild West - not to mention the course of American history - may never be the same!

Sleeping under a wagon, eating moldy beans, and driving oxen through a dusty desert - nobody ever said the Oregon Trail was going to be like this! But just when Phoebe Brown is sure she can't stand another day of her father and the other bossy male members of the wagon train, tragedy strikes. Suddenly, it is up to the women to decide: should they turn back to the life they left behind or push for Oregon on their own steam? For this spunky group of lady pioneers, the answer is clear. They're going to change Manifest Destiny into Wo-manifest Destiny - no matter what it takes!
