David Poyer's saga of Hemlock County explores that land where coal yielded to oil, the heart of American industrial power. This multi-volume work is also the life story of a powerful character, William Halvorsen, a tough, idealistic working man who lives in the shadow of, and sometimes in the employ of, Thunder Oil and its autocratic capitalist owner, Daniel Thunner. Halvorsen's times are times of violence, love, tragedy, betrayal, and triumph, hard times throughout, but always with the feeling that the struggle is worthwhile, that both pleasure and redemption are possible. This is the story of America's 20th century.

Winter Light collects Dead of Winter and As the Wolf Loves Winter. Thunder on the Mountain, which introduces Halvorsen, is available in mass market paperback.
