Since age sixteen, Bee has loaded freight for the Union Pacific Railroad, all the while dreaming of becoming an engineer. Bee loves being part of the railroad: the roar and clatter of the wheels against the track; the trains with names like the True Heart, the Roaring Wolf, and the Coyote Special; the low blast of the whistle - whooo. Then one day, Bee finally gets the chance to drive the True Heart all the way from Cheyenne to Chicago. And Bee's been driving the train ever since. True Heart is a story of the American frontier, and of wanting something so much you can't think of anything else. Put on your engineer's cap and get ready for the ride of your life. Whooooo. Whooooo.
