So I am an avid Game of Thrones fan. I am currently about to start book 3 whilst at the same time being fully up to date with the HBO show.
This weekend someone showed me this video on YouTube and it blew my mind. So much so that we had to make a T-shirt to celebrate it.
As long as you've seen season 2 then you should be OK for spoilers.
