I read a lot of books, but my favorite author is Isaac Asimov. His earth filled with robots makes me imagine about all the possibilities of the human race. Plus, I really liked his book "The End Of Eternity". After reading that, I got to know a little bit more about time travel!
Since I'm french canadian, I also read books from a french person called Patrick Senécal. His books starts off kinda normal at first and then turns COMPLETELY dark and grotesque (in one book, the protagonist is forced to torture a guy by putting his arm between the wheels of a bike, and then turns the wheel very fast
)
But, I also read a bunch of mangas and comic books, but I don't have any preferences, although I really like the "Watchmen" and "Liar Game" ^_^
