Matthew Wolfe’s Fires in the Night: The Earth Liberation Front, the FBI, and a Secret History of Eco-Sabotage is a compelling work of narrative nonfiction, meticulously researched and written with the tension of a thriller. Amid the stories of ELF members who stealthily committed arson in the name of animals and the planet are the stories of the law enforcement officers whom the Elves outwitted and outran at every step—until they didn’t. And underneath the drama is a stark message: the planet is imperiled, and those most passionate about saving it have been labeled terrorists.
