This book reads Revelation through the lens of the monster. Using monster theory, Heather Macumber approaches the cosmic beings in John's Apocalypse as other and monstrous regardless of whether they are found in heaven or the abyss, with significant attention paid to the monstrous body and how it causes both unease and wonder. Intertwined with descriptions of cosmic monsters, this book also interrogates the role of John as a maker of horror stories, who casts his opponents as the other and monstrous. Despite the tendency to view John and the heavenly creatures as the heroes of this apocalyptic tale, Macumber aims to recover their own liminal and hybrid characteristics that mark them as monstrous.
