The Challengers [EPUB ebook] 

The Challenger family pulls together when faced with desperate times. Father has been hospitalized for a long time, and money is hard to come by in the 1930s. Mother takes to her bed while Phyllis tries to manage her siblings and their income, but they may default on rent and lose their home in the middle of winter… unless a miracle happens. Can the Challengers hold on long enough to see an end to their troubles?
