This book explores the development of ecological awareness in Jeff VanderMeer's New Weird novels, focusing specifically on the Southern Reach (2014-2024) and Borne (2017-2019) series. As the first book-length study on VanderMeer's work to contextualize his novels through object-oriented ontology (OOO), an emerging branch of speculative philosophy that investigates how things exist, this work enables a uniquely experimental reading of VanderMeer: one that accentuates how his work unsettles what is perceived as normal and exposes the bounds of human reasoning, as well as how we understand ourselves and our relationships with nonhumans.
