The Functions of Unnatural Death in Stephen King: Murder, Sickness, and Plots examines over thirty of King's works and looks at the character deaths within them, placing them first within the chronology of the plot and then assigning them a function. Death is horrific and perhaps the only universal horror because it comes to us all. Stephen King, known as the Master of Horror, rarely writes without including death in his works. However, he keeps death from being repetitious or fully expected because of the ways in which he plays with the subject, maintaining what he himself has called a childlike approach to death. Although character deaths are a constant, the narrative function of those deaths changes depending on their placement within the plot.

By separating out the purposes of early deaths from those that come during the rising action or during the climax, this book examines the myriad ways character deaths in King can affect surviving characters and therefore the plot. Even though character deaths are frequent and hardly ever occur only once in a book, King's varying approaches to, and uses of, these deaths show how he continues to play with both the subject and its facets of horror throughout his work.
