Query: A realistic, dramatic book

I think an author has done his job when I want to enter the pages of his novel and talk to his characters. That's a testament to the complexity and realism of the personas you meet in this book, and to the vividness and high stakes of the struggles they face. Aside from that, no writer I know has a keener eye than Mr. Poyer for details that create verisimilitude. I was not alive in 1936, I have never been to Pennsylvania, never been to an oil field or oil refinery, and never participated in a hard-fought wildcat strike. But after reading this book I felt like I had been there.
