Looking for Alaska - John Green. I love the way John Green writes. I may not always be happy with what is going on in the story, but I am always happy to read more of his words. I loved the obsession with last words and the references to beloved poems!
Meredith: The Fault in Our Stars: John Green. Moving towards more modern books, my favorite "new" book is definitely The Fault in Our Stars. It's extremely sad but, in actuality, quite well written for YA lit.
