Just spoil it for yourself by reading the books! It's totally worth the time investment.
I don't really have time to read comic books so reading a series of novels is pretty much out of the question at the moment lol. Plus I am afraid to read them because I like being surprised by the show, not knowing anything about the storyline of the books. Same thing with The Walking Dead. I can't read the books until the show is over since i started the show first. I don't want to have conflicting continuities or little things they changed rolling around in my head causing me to nitpick everything all the time. It would ruin it for me I think.
It's like when I read the Jurassic Park novels before I saw the movies. The first movie was great because they stuck pretty close to the book (they did change some things which bugged me, but it still was awesome). BUT when it comes to the second movie, I HATE IT because pretty much nothing from the book was in the movie. It's like 1 scene that ran for 5 minutes was in the movie and they ignored the rest of the book. It kind of sucks because I know people that really like the 2nd movie, but I just can't do it because of how much they strayed from the book.
Same thing with Queen of the Damned (holy crap that was a turd of a movie)
