Question: how is a fiction book better than a nonfiction book?? 

Answer: In a fictional book, you don't have to worry about accuracy as far as writing it.  You can make up whatever you want.  As far as reading it, you aren't too concerned with historical accuracy unless you're a Middle Earth nerd and know everything there is to know about the Elven race...including who fathered who(it's seems about as ridiculous as Leviticus at times).  You can imagine fictional animals and such...and the images won't be ruined unless you see a movie about the book.
