True Heart — Marissa Moss

Since age sixteen, Bee has loaded freight for the Union Pacific Railroad, all the while dreaming of being an engineer. Bee loves the railroad: from the roar and clatter of the wheels against the track to the names like True Heart, Roaring Wolf, and Coyote Special to the low blast of the whistle -- whoooo-whoooo. Then one day, Bee gets the chance to drive the True Heart all the way from Cheyenne to Chicago. A seamless mix of history and fiction, True Heart is a story of the American frontier, of wanting something so much you can't think of anything else--and of the little-known work of pioneer women who made the American railroad a reality.
