When the Killing's Done - Tom Coraghessan Boyle

Alma Boyd Takesue is a National Park Service biologist who is spearheading the efforts to save the island's endangered native creatures from invasive species like rats and feral pigs, which, in her view, must be eliminated. Her antagonist, Dave LaJoy, is a dreadlocked local businessman who, along with his lover, the folksinger Anise Reed, is fiercely opposed to the killing of any species whatsoever and will go to any lengths to subvert the plans of Alma and her colleagues. T.C. Boyle is the New York Times bestselling author of The Women and Wild Child, among others.
