"Horror is a polarizing genre. While one group of readers might find the suspense of each plot exciting, others may find the content too disturbing and avoid the genre altogether. Other readers fall in the middle, tending to go back and forth between the two extremes. If you are a regular reader of the genre, you probably know that some of the best horror books trigger a visceral reaction, which is why authors like Stephen King and Mary Shelley are well-respected for this craft."
