Brandon Hawks considers the fictional Sixteenth Century Serbian book that puts the Santa Clarita Diet‘s zombie disease in historical context. (And he teaches everyone more about mixed media manuscript-print books). “While the book is a plot device, pointing to the mysteries of the disease’s origins centuries before, its details are a treasure for book nerds. The book is most prominent in the episode where it’s introduced, but it also keeps appearing throughout the two seasons of the show released so far. A few times, the main characters go back to it to consult for more clues about the zombie disease.”
