Growing up in Pennsylvania coal country, writer Jennifer Haigh learned that a lot of what matters in the state can't be seen. It lies beneath the surface, in the form of potential energy. She saw how the boom and bust cycles of mining affected the people of her hometown, which is now poised on the brink of fracking.
She's taken what she knows and turned it into a new novel, Heat and Light. But Haigh says she doesn't think of it as a book about fracking.
