A Clash of Kings - George R.R. Martin
I'm completely and utterly hooked on this series. There's so much in here, I don't even know where to start on what I love about it.

It is very involved and frustrating when the perspective shifts characters. Having maps of this world and a list of the players is very helpful to keep them all straight.

I do feel it should be noted for Trigger Warning due to rape being common in the series.

I'm at a loss on what else to add. I feel so inadequate when talking about this series. It's on my list of all time favorites already. I hope the next books live up to it.
