Answer
Hayduke Lives!, Edward Abbey's semi-sequel to The Monkey Wrench Gang, continues the exploits of the cantankerous environmental activist George Hayduke as he leads his friends on various eco-sabotage missions to protect the wilderness from the encroaching forces of industrial development in the Western United States. With its satirical humor, sharp social commentary, and thrilling action scenes, Hayduke Lives! is a quintessential work of environmental literature.
