What happens when the environment fights back? Three authors of this year’s breathtaking eco-thrillers read and discuss their work. Tara Campbell’s novel TreeVolution explores eco-payback and technology’s role in conservation when trees begin making violent assaults on humans. Elizabeth Hand’s collection Fire combines fiction and nonfiction to tell tales of everything from post-apocalyptic terror to time-travel romance. JJ Amaworo Wilson’s novel Damnificados portrays an derelict tower in Venezuela occupied by vagabonds whose thriving, if makeshift community, must face a brutal army and a Biblical flood.
