Horror is a genre of literature that is designed to evoke feelings of fear, terror, and dread in the reader. It typically features supernatural or paranormal elements, such as ghosts, monsters, or otherworldly creatures, and often explores themes of death, violence, and the unknown. Horror books can range from subtle and psychological to graphic and gory, but they all share the common goal of scaring and thrilling their readers. Whether it's a classic ghost story or a modern slasher novel, horror books offer a unique and thrilling reading experience for those who enjoy being scared out of their wits.

The "Investigation" category of books typically involves stories that revolve around solving a mystery or crime. These books often feature detectives, private investigators, or other types of sleuths who use their skills and expertise to uncover clues, interview suspects, and ultimately solve the case. The investigation genre can include a wide range of sub-genres, such as police procedurals, cozy mysteries, and psychological thrillers, but all share a common focus on the process of uncovering the truth.
