ANYTHING by Jodi Picoult is amazing. By far My Sister's Keeper is the best one. I've read Picture Perfect, Salem Falls, My Sister's Keeper, Second Glance, and The Pact.
Also, Nicholas Sparks is awesome too. I'm reading Dear John right now and it's really good. He wrote The Notebook and A Walk to Remember. I also read The Guardian which was so good.
Needless to say, I love reading. I am on my ninth book of the summer. But seriously, try those 2 authors, you won't regret it!
