Delirium  - Lauren Oliver

This book scared me more than 1984, if you can believe that. Oliver's world without love is disturbing and stuck with me long after I finished the book. The story sucked me in and I liked the characters. Even more striking: I was on board with this book all the way through, but when I reached the final page I was blown away. I can't remember the last time I finished a book and was genuinely surprised. I can't wait for the sequel.
