Why not have your mystery and enjoy some sci-fi (or fantasy, or romance, or horror) too? With these genre-blending mystery books, you don’t have to choose! You don’t have to stick to only one genre when you can have two or even three at once. That’s the beauty of genre-blending. Books that blend and defy genres don’t have to stick to typical conventions. A locked room murder mystery can become a locked spaceship murder mystery, and a cozy mystery can become a cozy mystery rom-com.
If you ask me, stories are just more fun when they take big swings and don’t try to stick to expected norms. These eight genre-blending mystery books never stick with the ordinary or expected. Instead, they choose to have their genre cake–and eat it too!
Genre-Blending Mystery Novels
Mystery + Sci-Fi
Murder by Memory by Olivia WaiteOn an interstellar cruise ship where memories can be saved in the library and bodies can be swapped on request, Dorothy Gentleman wakes in a body that isn’t her own just as a dead body is discovered, clearly murdered. As one of the ship’s detectives, Dorothy normally relishes a good mystery. But when she discovers someone is deleting minds from the library as well as killing passengers, it’s clear something far darker is afoot. Could it be the fault of her kind but feckless nephew? Or perhaps the beautiful yarn store proprietor who once dated the body she’s inhabiting? Either way, Dorothy will have to get to the bottom of it before anyone else is gotten rid of—permanently. |
