No one can pick out a specific book and know that they like it based on genre.
My favorite genres, I don’t have one. Usually I will skip from genre to genre, if I like the book then I like it.
Fantasy; Harry Potter, Percy Jackson, Kane Chronicles, Heroes of Olympus, The Mortal Instruments
Realistic Fiction; Ask the Passengers, Please Ignore Vera Dietz, Beholding Bee, The Running Dream
Fiction; Vessel, Angelfire, Nevermore, Defiance
Some examples I’ve read
