Different Book Genres

Alrighty, folks, my father recommended describing the different genres to you people who aren't bookworms for future references I might make.
Fantasy: Not real, fiction. most of these books are set in medieval times. they often include knights, kings, vampires, werewolves, wizards, dragons,...etc.
Historical Fiction: These stories mostly take place in actual historical events, however, they do not involve the perspective of an actual historical character. 
Realistic Fiction: These are stories that could actually happen, but are not based on a true story.
Biography: A book written about someone. It can be a famous celebrity or a historical figure. Don't confuse with autobiography!
Mystery: You will always be caught by surprise by these books. Usually, they start with a character trying to solve a code or something and at the end, they figure it out or they reveal the bad guy.
Horror: Basically, it's in the name. The scary, don't read at night books. sometimes confused with mystery.
Autobiography: Like a biography, these books are about an important person, only that person wrote the book themselves. Kind of like a diary, they just share stories about themselves. A good example would be The Diary Of Anne Frank.
Nonfiction: These can be about historical events or just plain facts. If you need information for a research project, this would be the place to go. You'll find the books can range from encyclopedias to King Arthur and His Knights.
Sci-fi: Usually fiction that is explained by or involves a lot of science. Space mainly.
Adventure: Yes, I'm sure some of these other Boom genres are full of adventures, but these are non stop adventure. Either that or there was nothing fake so they couldn't identify it as fantasy.
Romance: Alright this is a shout out for all you Hallmark lovers and teenage girls. From start to finish, you read about a slow romance blossoming and on the last page, the main characters get married. Usually, they are very predictable, so I don't often read them.
Dystopian: I don't know why I love these books so much, but basically they take place in a horrifying future. To give you an idea, one example is the Hunger Games or The Maze Runner Series.
Graphic Novels: Just a fancy title for comic books. There are a lot of pictures and few words. Not exactly a picture book.
