Tyson E. Lewis and Richard Kahn argue for a new critical theory of the monster as an imaginary other on the margins of human and animal. Through a unique combination of critical, posthumanist, and educational theories, the authors engage in a surreal journey into the worlds of feral children, alien reptoids, and faery faiths in order to understand how social movements are renegotiating the boundaries of community. Part philosophy of imagination, part political theory, and part pedagogical critique, this book is a twenty-first century bestiary - a catalog to navigate the monstrous world in which we live.
