Just started A Feast for Crows, read the prologue. I'm gonna talk Storm of Swords ending though.
Spoiler!!! Click to Read!:
So legit when Tyrion killed Tywin and Shae. Tyrion is one of my favorite characters, which means he'll probably die at some point.
I was also glad when Littlefinger killed Lysa, she sucked. I'm predicting Arya is gonna become a badass assassin. I'm also pumped that Storm of Swords made Jaime into a likable character, which is amazing considering he pushed a boy off a tower in attempted murder, and he bangs his own sister. Friggin awesome series.
