1. A Storm of Swords: While all the ASoIF books are worthy of a spot in my top 5 books of all time, ASoS is by far the best. It provided some of the best insight into not only the main characters and there motivations, but the secondary and minor characters. While not wishing to spoil, some of the plots designed by the secondary characters has left me speechless and honestly I cannot look at the series the same way. Also I'd like to say the fact that no one appeared safe no matter how important has also made me question which characters I get invested in.
2. Brave New World: This book is just fantastic, very depressing, but fantastic. Comparing it to the other Dystopian future novel that I've read, this one is just miles ahead in my opinion. What it did that I really enjoyed, was that while the characters were relatable, they had a number of alien qualities that I believe set them apart from other protagonist and deuteragonist. Plus the ending honestly made me cry.
3. Point of Origin: This book in my opinion would have to have been Patricia Cornwell best. It was griping suspenseful and above all else immersive. I've read a number of her books, but this is by far the most engrossing and well written of her vast bibliography.
4. Pride and Prejudice: This book really surprised me when I read it. Not thinking anything of it beforehand, I was shocked by just how much I liked all the characters, like in this meaning I liked their character arcs and development not necessarily actually being fond of the characters. I think what I enjoyed most of all, is how it played on the presupposed stereotypes we develop of characters giving a rich human quality to all the characters and not just another boring cliched romance novel.
5. The Deathly Hallows: This book is only in my top five, because of 1 scene, Snape's Death scene (If you haven't seen this yet or read it then that's your problem). In my opinion this was the best scene not only from this book, but the entire series. In one scene, it changes Snape from the perceived villain he's been throughout the novel and turned him into the best by far.
