Alternate History is a genre of fiction that explores the possibilities of what could have happened if certain historical events had taken a different course. It involves imagining a world where key moments in history have been altered, resulting in a different outcome. This genre often blends elements of science fiction, fantasy, and historical fiction, and can provide thought-provoking insights into the impact of historical events on our present-day world.

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.
