First time reader of GOT…. Suggestions?

I’m ready to take the plunge and read the series. I hadn’t before because it felt so intimidating and I wasn’t much of a fantasy fan. Now that I’ve dipped my toe in reading some fantasy, I think I’m ready to give it a try. I watched the series years ago and like most loved it! However it’s been long enough that I believe the reading will be a different and almost introductory experience. (I don’t remember a whole lot from the show) Any suggestions on how to tackle this? Did others feel like this was a massive undertaking? lol
