1. A Storm Of Swords
If A Game of Thrones is perfect, then there really is no way to describe A Storm of Swords, considered the best book almost undisputedly by most fans. This book had everything. If A Clash Of Kings was action heavy and A Game of Thrones was plotting heavy, then A Storm of Swords had just the right amount of both. It really pushed the bounds of fiction in a lot of ways. The complete turn around of Jaime Lannister into one of the most beloved characters is something only an amazing author could do. The now infamous Red Wedding which offs more than half the characters was the kind of thing that made me literally throw the book against a wall, scream, but pick it up five minutes later. The wedding of Joffrey and Margaery, the wedding of Sansa and Tyrion, the escape of Sansa, the Trial of Tyrion, the Battle for the Wall, Tywin being a badass, Olenna Tyrell, Arya and the Hound, Bran and the warg, Jaime and Brienne and the Bear, all of it came together in a literally perfect book where one epic event happens right after the other and the audience can't wait to turn the page. I can honestly say I have never read a better book. This is just a perfect book and if you haven't read it or any of the books in the series, then you should, because you're missing out.
