The Twins and the Wild West — Francine Pascal

Jessica and Elizabeth Wakefield and their brother, Steven, are visiting Wild West Town with Grandma and Grandpa Wakefield.  It's the best trip they've ever taken.  First they change into Western costumes to get into the spirit of the old days.  Then they eat in a saloon, visit a mine, and pan for gold!  On their way back to town, their stagecoach is held up by the meanest outlaw Wild West Town has ever seen.  Steven has been bragging all weekend about how brave he is.  Will he be the hero?  Or will Jessica and Elizabeth save the day?
