Brandon Sanderson.

I empathize, I went through something similar. I picked up ASOIAF without realizing the series wasn't finished yet (predating the show by a year or two). When I reached the end of book 4, it had a little note about how some plot lines had been moved out of #4 and would show up in #5, which would come out shortly. Then I looked at the publication date, and thought "not again".

They're still enjoyable to read, and I think Neil's got the right attitude.

Personally, I think the show will catch, and pass, the novels, and it will become canon. And I'm okay with that too.
