The White Stallion by Elizabeth Strub
 
Long ago, in 1845, a young girl named Gretchen and her family were on their way west. One day, the horse Gretchen was riding strayed far away from the wagon train. Gretchen was lost and all alone. But then a magnificent white stallion appeared. And Gretchen knew she didn't have to be afraid, because the beautiful horse would show her the way back home.
