Racial intolerance, social change, and sweeping progress make 1908 Washington, D.C., a turbulent place to grow up in for 12-year-old Emily Soper. For Emily, life in Papa's carriage barn is magic, and she's more at home hearing the symphony of the blacksmith's hammer than trying to conform to the proper expectations of young ladies. When Papa's livelihood is threatened by racist neighbors and horsepower of a different sort, Emily faces changes she'd never imagined. Finding courage and resolve she didn't know she had, Emily strives to save Papa's business, even if it means going all the way to the White House.
