In 1914, Andrew Houghton's family is one of hundreds eking out an existence in the coal mines of southwestern Pennsylvania. Though he longs to be a veterinarian, he's fated for a life underground, picking rock alongside his father. That destiny changes when his aunt, Eveline Kiser, arranges for her husband to secure Andrew an apprenticeship on the railroad. Wilhelm Kiser, a German immigrant, has found his American dream in Pittsburgh, with a well-paying job as a brakeman, and a secure pension. But on Andrew's first week, an incident goes tragically wrong, leaving him severely injured, his dreams shattered. Wracked with guilt, Wilhelm finally agrees to his wife's pleas to leave Pittsburgh's smog behind. With Andrew in tow, they swap their three-story row house for a rough-and-tumble farm. Life in rural Pennsylvania is not as idyllic as Eveline imagined. The soil is slow to yield and their farmhouse is in disrepair. But there is one piece of beauty in this rugged land. Lily Morton is quick-witted and tough on the outside, but bears her own secret scars inside. Andrew's bond with her will help steer them through all the challenges to come, even as anti-German sentiment spreads across America with the outbreak of World War I.
