I'm looking for books (fiction) about people in their twenties, preferably between 20-25. Maybe I've been looking in the wrong places, but I find that these books are kind of hard to come by.
The genres I enjoy are science fiction, fantasy, crime, horror and general fiction. A little romance is okay, as long as it isn't the only plot-line.
EDIT: To specify a bit: Please, rec me your favourite book(s) with a protagonist in his/her twenties :)
