I like some nonfiction but my favorite topic in nonfiction is science-fiction.  I like science-fiction becuase it could be about 17 different things from aliens-to-robots. And the best part about it it contains fiction and nonfiction!  Science-Fiction is a genre that is dealing with stuff that could happen, but are pobably not really going to.  The modern day Science-Fiction was made during the Industrial Revolution, and will not be replaced by a new type soon.
