I think authors are just realizing there's no real reason to feel limited to a narrow set of genre rules in their writing. There's no reason a mystery novel can't have fantastic elements in it. Similarly, there's no reason why your epic fantasy series can't have elements of a mystery.
Patrick RothfussIf you're going to have a book full of clever people and nobody ever jokes, it's just not going to ring true to the reader. That said, humor writing is the hardest kind of writing there is.
Patrick RothfussWords are pale shadows of forgotten names. As names have power, words have power. Words can light fires in the minds of men. Words can wring tears from the hardest hearts. There are seven words that will make a person love you. There are ten words that will break a strong man's will. But a word is nothing but a painting of a fire. A name is the fire itself.
