I go through periods where I cannot force myself to read a fiction book. During these periods, I even have a hard time watching a movie (though documentaries I tend to just eat up during them) I read science books, philosophy books, psychology books and stuff of the like...
Other times, I do read fiction. But for the most part, it's all one genre, and could even be more narrowly defined.
Terry Goodkind, Robert Jordan, David Eddings come to mind quickly.
Epic Fantasy I guess would be what you'd call it... battle between the child of the light and the child of the dark.
I think I like to read it, because they're so good at putting all the bullcrap religious rites and rituals and beliefs into a different light that look so silly, and that the reader, if they possess any intelligence can see for the discrimination, bigotry and "evil" that they are. I also like the ones that really like to obscure the line between the light- and the dark-sides.
