The Buffalo's Last Stand - Retta Barre's Oregon Trail, #2

Retta Barre has never met a hero, except for the ones she reads around in her books. She does know they're strong and courageous. And handsome and pretty. Everything she's not. Her world doesn't expect much from her anyway. She's just a plain-looking 12-year-old who's more stubborn than brave. She owes what little strength she has to her dull daily chores on the Oregon trail. And yet, when her friends are missing, Retta doesn't think twice.
She heads out to help them. She has no idea the danger that's about to come her way. She'll have to face her fears and act like the heroes she reads about in her novels.
