I adore George RR Martin's A Song of Ice and Fire series. I love the HBO series based on it, Game of Thrones. Last time, I read the book (LOVED IT) and watched the first season of the series after I read a chapter or two. It was helpful because there were so many characters and story lines going on, watching it play out on the TV clarified things in my head.
This season I'm going to watch the episodes first and then read the part in the book. I'm interested to see how my enjoyment differs.
