Stephen King is no stranger to the realm of literary criticism, but his most fantastic, far-reaching work has aroused little academic scrutiny. This study of King's epic Dark Tower series encompasses the career of one of the world's best-selling authors and frames him as more than a "horror writer." Four categories of analysis--genre, art, evil, and intertextuality--provide a focused look at the center of King's fictional universe. This book reaches beyond popular culture treatments of the series and examines it against King's horror work, audience expectations, and the larger literary landscape.
