Read about the other entries on the list.Nick and Amy Dunne, Gone Girl
Not to spoil it for the 2.3% of people who have not yet read this book, but Nick and Amy Dunne (oh, especially Amy) are not the most trustworthy of sources. Twists and turns and deliberate deceit turn the story on its head, and readers are shocked because Flynn is toying with our ability to discern reliability.
Sam Thomas "absolutely loved ... Gone Girl by Gillian Flynn.... I’m a sucker for unreliable narrators, and without spoiling too much, I think it’s safe to say that both of Girl’s narrators fit that description."
