Gold-Rush Phoebe (Petticoat Party #4)

In 1848, fifteen-year-old Phoebe Brown disguises herself as a boy and runs away with her friend Robbie Robson to join in the California gold rush. Along the way to Sutter's Mill they encounter all sorts of mishaps, but Phoebe has survived the hardships of the Oregon Trail, and she's ready to handle any adventure that comes her way -- except maybe romance.
